| CVE-2023-3389 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable). | ||||
| CVE-2023-3090 | 3 Debian, Linux, Redhat | 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more | 2025-02-13 | 7.8 High |
| A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to achieve local privilege escalation. The out-of-bounds write is caused by missing skb->cb initialization in the ipvlan network driver. The vulnerability is reachable if CONFIG_IPVLAN is enabled. We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. | ||||
| CVE-2023-34324 | 2 Linux, Xen | 2 Linux Kernel, Xen | 2025-02-13 | 4.9 Medium |
| Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by removal of a paravirtual device on the other side. As this action will cause console messages to be issued on the other side quite often, the chance of triggering the deadlock is not neglectable. Note that 32-bit Arm-guests are not affected, as the 32-bit Linux kernel on Arm doesn't use queued-RW-locks, which are required to trigger the issue (on Arm32 a waiting writer doesn't block further readers to get the lock). | ||||
| CVE-2023-34319 | 3 Debian, Linux, Xen | 3 Debian Linux, Linux Kernel, Xen | 2025-02-13 | 7.8 High |
| The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a way such that not all of the headers would come in one piece. Unfortunately the logic introduced there didn't account for the extreme case of the entire packet being split into as many pieces as permitted by the protocol, yet still being smaller than the area that's specially dealt with to keep all (possible) headers together. Such an unusual packet would therefore trigger a buffer overrun in the driver. | ||||
| CVE-2023-30449 | 5 Hp, Ibm, Linux and 2 more | 7 Hp-ux, Aix, Db2 and 4 more | 2025-02-13 | 7.5 High |
| IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to denial of service with a specially crafted query. IBM X-Force ID: 253439. | ||||
| CVE-2023-30448 | 5 Hp, Ibm, Linux and 2 more | 6 Hp-ux, Aix, Db2 and 3 more | 2025-02-13 | 5.9 Medium |
| IBM DB2 for Linux, UNIX and Windows (includes Db2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to denial of service with a specially crafted query on certain tables. IBM X-Force ID: 253437. | ||||
| CVE-2023-30445 | 5 Hp, Ibm, Linux and 2 more | 7 Hp-ux, Aix, Db2 and 4 more | 2025-02-13 | 7.5 High |
| IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 10.5, 11.1, and 11.5 is vulnerable to denial of service with a specially crafted query on certain tables. IBM X-Force ID: 253357. | ||||
| CVE-2023-2236 | 2 Linux, Netapp | 2 Linux Kernel, Hci Baseboard Management Controller | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Both io_install_fixed_file and its callers call fput in a file in case of an error, causing a reference underflow which leads to a use-after-free vulnerability. We recommend upgrading past commit 9d94c04c0db024922e886c9fd429659f22f48ea4. | ||||
| CVE-2023-1998 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.6 Medium |
| The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects. | ||||
| CVE-2023-1872 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local privilege escalation. The io_file_get_fixed function lacks the presence of ctx->uring_lock which can lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8. | ||||
| CVE-2023-1829 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. | ||||
| CVE-2023-1281 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-02-13 | 7.8 High |
| Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. | ||||
| CVE-2023-0266 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-02-13 | 7.9 High |
| A use after free vulnerability exists in the ALSA PCM package in the Linux Kernel. SNDRV_CTL_IOCTL_ELEM_{READ|WRITE}32 is missing locks that can be used in a use-after-free that can result in a priviledge escalation to gain ring0 access from the system user. We recommend upgrading past commit 56b88b50565cd8b946a2d00b0c83927b7ebb055e | ||||
| CVE-2023-0045 | 3 Debian, Linux, Netapp | 13 Debian Linux, Linux Kernel, Active Iq Unified Manager and 10 more | 2025-02-13 | 4.7 Medium |
| The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to the prctl syscall. The patch that added the support for the conditional mitigation via prctl (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit a664ec9158eeddd75121d39c9a0758016097fa96 | ||||
| CVE-2022-47986 | 3 Ibm, Linux, Microsoft | 3 Aspera Faspex, Linux Kernel, Windows | 2025-02-13 | 9.8 Critical |
| IBM Aspera Faspex 4.4.2 Patch Level 1 and earlier could allow a remote attacker to execute arbitrary code on the system, caused by a YAML deserialization flaw. By sending a specially crafted obsolete API call, an attacker could exploit this vulnerability to execute arbitrary code on the system. The obsolete API call was removed in Faspex 4.4.2 PL2. IBM X-Force ID: 243512. | ||||
| CVE-2022-2196 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.8 Medium |
| A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past commit 2e7eab81425a | ||||
