| In the Linux kernel, the following vulnerability has been resolved:
riscv: kvm: fix vector context allocation leak
When the second kzalloc (host_context.vector.datap) fails in
kvm_riscv_vcpu_alloc_vector_context, the first allocation
(guest_context.vector.datap) is leaked. Free it before returning. |
| A vulnerability was determined in haojing8312 WorkClaw up to 0.6.4. This affects the function is_dangerous of the file apps/runtime/src-tauri/src/agent/tools/bash.rs of the component Blacklist Handler. Executing a manipulation can lead to os command injection. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: smartpqi: Fix memory leak in pqi_report_phys_luns()
pqi_report_phys_luns() fails to release the rpl_list buffer when
encountering an unsupported data format or when the allocation for
rpl_16byte_wwid_list fails. These early returns bypass the cleanup logic,
leading to memory leaks.
Consolidate the error handling by adding an out_free_rpl_list label and use
goto statements to ensure rpl_list is consistently freed on failure.
Compile tested only. Issue found using a prototype static analysis tool and
code review. |
| In the Linux kernel, the following vulnerability has been resolved:
8021q: delete cleared egress QoS mappings
vlan_dev_set_egress_priority() currently keeps cleared egress
priority mappings in the hash as tombstones. Repeated set/clear cycles
with distinct skb priorities therefore accumulate mapping nodes until
device teardown and leak memory.
Delete mappings when vlan_prio is cleared instead of keeping tombstones.
Now that the egress mapping lists are RCU protected, the node can be
unlinked safely and freed after a grace period. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/mana: Fix error unwind in mana_ib_create_qp_rss()
Sashiko points out that mana_ib_cfg_vport_steering() is leaked, the normal
destroy path cleans it up. |
| A flaw has been found in Totolink A8000RU 7.1cu.643_b20200521. The impacted element is the function setL2tpServerCfg of the file /cgi-bin/cstecgi.cgi of the component Web Management Interface. Executing a manipulation of the argument enable can lead to os command injection. The attack can be executed remotely. The exploit has been published and may be used. |
| A flaw has been found in Totolink A8000RU 7.1cu.643_b20200521. This vulnerability affects the function setOpenVpnCertGenerationCfg of the file /cgi-bin/cstecgi.cgi of the component Web Management Interface. Executing a manipulation of the argument servername can lead to os command injection. The attack may be launched remotely. The exploit has been published and may be used. |
| A weakness has been identified in Totolink CA750-PoE 6.2c.510. This issue affects the function NTPSyncWithHost of the file /cgi-bin/cstecgi.cgi of the component Setting Handler. Executing a manipulation of the argument host_time can lead to os command injection. The attack can be launched remotely. The exploit has been made available to the public and could be used for attacks. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Limit bpf program signature size
Practical BPF signatures are significantly smaller than
KMALLOC_MAX_CACHE_SIZE
Allowing larger sizes opens the door for abuse by passing excessive
size values and forcing the kernel into expensive allocation paths (via
kmalloc_large or vmalloc). |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: ns: Free the node during ctrl_cmd_bye()
A node sends the BYE packet when it is about to go down. So the nameserver
should advertise the removal of the node to all remote and local observers
and free the node finally. But currently, the nameserver doesn't free the
node memory even after processing the BYE packet. This causes the node
memory to leak.
Hence, remove the node from Xarray list and free the node memory during
both success and failure case of ctrl_cmd_bye(). |
| In the Linux kernel, the following vulnerability has been resolved:
spi: fix resource leaks on device setup failure
Make sure to call controller cleanup() if spi_setup() fails while
registering a device to avoid leaking any resources allocated by
setup(). |
| In the Linux kernel, the following vulnerability has been resolved:
spi: ch341: fix memory leaks on probe failures
Make sure to deregister the controller, disable pins, and kill and free
the RX URB on probe failures to mirror disconnect and avoid memory
leaks and use-after-free.
Also add an explicit URB kill on disconnect for symmetry (even if that
is not strictly required as USB core would have stopped it in the
current setup). |
| In the Linux kernel, the following vulnerability has been resolved:
mm/damon/stat: fix memory leak on damon_start() failure in damon_stat_start()
Destroy the DAMON context and reset the global pointer when damon_start()
fails. Otherwise, the context allocated by damon_stat_build_ctx() is
leaked, and the stale damon_stat_context pointer will be overwritten on
the next enable attempt, making the old allocation permanently
unreachable. |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: ns: Limit the maximum number of lookups
Current code does no bound checking on the number of lookups a client can
perform. Though the code restricts the lookups to local clients, there is
still a possibility of a malicious local client sending a flood of
NEW_LOOKUP messages over the same socket.
Fix this issue by limiting the maximum number of lookups to 64 globally.
Since the nameserver allows only atmost one local observer, this global
lookup count will ensure that the lookups stay within the limit.
Note that, limit of 64 is chosen based on the current platform
requirements. If requirement changes in the future, this limit can be
increased. |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: fix memory leaks in gfs2_fill_super error path
Fix two memory leaks in the gfs2_fill_super() error handling path when
transitioning a filesystem to read-write mode fails.
First leak: kthread objects (thread_struct, task_struct, etc.)
When gfs2_freeze_lock_shared() fails after init_threads() succeeds, the
created kernel threads (logd and quotad) are never destroyed. This
occurs because the fail_per_node label doesn't call
gfs2_destroy_threads().
Second leak: quota bitmap buffer (8192 bytes)
When gfs2_make_fs_rw() fails after gfs2_quota_init() succeeds but
before other operations complete, the allocated quota bitmap is never
freed.
The fix moves thread cleanup to the fail_per_node label to handle all
error paths uniformly. gfs2_destroy_threads() is safe to call
unconditionally as it checks for NULL pointers. Quota cleanup is added
in gfs2_make_fs_rw() to properly handle the withdrawal case where
quota initialization succeeds but the filesystem is then withdrawn.

| In the Linux kernel, the following vulnerability has been resolved:
nfsd: never defer requests during idmap lookup
During v4 request compound arg decoding, some ops (e.g. SETATTR)
can trigger idmap lookup upcalls. When those upcall responses get
delayed beyond the allowed time limit, cache_check() will mark the
request for deferral and cause it to be dropped.
This prevents nfs4svc_encode_compoundres from being executed, and
thus the session slot flag NFSD4_SLOT_INUSE never gets cleared.
Subsequent client requests will fail with NFSERR_JUKEBOX, given
that the slot will be marked as in-use, making the SEQUENCE op
fail.
Fix this by making sure that the RQ_USEDEFERRAL flag is always
clear during nfs4svc_decode_compoundargs(), since no v4 request
should ever be deferred. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/mempolicy: fix memory leaks in weighted_interleave_auto_store()
weighted_interleave_auto_store() fetches old_wi_state inside the if
(!input) block only. This causes two memory leaks:
1. When a user writes "false" and the current mode is already manual,
the function returns early without freeing the freshly allocated
new_wi_state.
2. When a user writes "true", old_wi_state stays NULL because the
fetch is skipped entirely. The old state is then overwritten by
rcu_assign_pointer() but never freed, since the cleanup path is
gated on old_wi_state being non-NULL. A user can trigger this
repeatedly by writing "1" in a loop.
Fix both leaks by moving the old_wi_state fetch before the input check,
making it unconditional. This also allows a unified early return for both
"true" and "false" when the requested mode matches the current mode.

drm/amdgpu: Fix memory leak in amdgpu_ras_init()
When amdgpu_nbio_ras_sw_init() fails in amdgpu_ras_init(), the function
returns directly without freeing the allocated con structure, leading
to a memory leak.
Fix this by jumping to the release_con label to properly clean up the
allocated memory before returning the error code.
Compile tested only. Issue found using a prototype static analysis tool
and code review. |

zram: do not forget to endio for partial discard requests
As reported by Qu Wenruo and Avinesh Kumar, the following
getconf PAGESIZE
65536
blkdiscard -p 4k /dev/zram0
takes literally forever to complete. zram doesn't support partial
discards and just returns immediately w/o doing any discard work in such
cases. The problem is that we forget to endio on our way out, so
blkdiscard sleeps forever in submit_bio_wait(). Fix this by jumping to
end_bio label, which does bio_endio(). |

SUNRPC: auth_gss: fix memory leaks in XDR decoding error paths
The gssx_dec_ctx(), gssx_dec_status(), and gssx_dec_name()
functions allocate memory via gssx_dec_buffer(), which calls
kmemdup(). When a subsequent decode operation fails, these
functions return immediately without freeing previously
allocated buffers, causing memory leaks.
The leak in gssx_dec_ctx() is particularly relevant because
the caller (gssp_accept_sec_context_upcall) initializes several
buffer length fields to non-zero values, resulting in memory
allocation:
struct gssx_ctx rctxh = {
.exported_context_token.len = GSSX_max_output_handle_sz,
.mech.len = GSS_OID_MAX_LEN,
.src_name.display_name.len = GSSX_max_princ_sz,
.targ_name.display_name.len = GSSX_max_princ_sz
};
If, for example, gssx_dec_name() succeeds for src_name but
fails for targ_name, the memory allocated for
exported_context_token, mech, and src_name.display_name
remains unreferenced and cannot be reclaimed.
Add error handling with goto-based cleanup to free any
previously allocated buffers before returning an error. |
