CVE-2024-1552 4 Debian, Linux, Mozilla and 1 more 9 Debian Linux, Linux Kernel, Firefox and 6 more 2025-03-27 7.5 High
Incorrect code generation could have led to unexpected numeric conversions and potential undefined behavior.*Note:* This issue only affects 32-bit ARM devices. This vulnerability affects Firefox < 123, Firefox ESR < 115.8, and Thunderbird < 115.8.
CVE-2023-31084 5 Debian, Fedoraproject, Linux and 2 more 8 Debian Linux, Fedora, Linux Kernel and 5 more 2025-03-18 5.5 Medium
An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event, down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and down(&fepriv->sem) may block the process.
CVE-2023-34256 3 Debian, Linux, Suse 3 Debian Linux, Linux Kernel, Linux Enterprise 2025-03-11 5.5 Medium
An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an offset. NOTE: this is disputed by third parties because the kernel is not intended to defend against attackers with the stated "When modifying the block device while it is mounted by the filesystem" access.
CVE-2023-3090 3 Debian, Linux, Redhat 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more 2025-03-05 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-2023-31248 5 Canonical, Debian, Fedoraproject and 2 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2025-03-05 7.8 High
Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()` failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace
CVE-2023-3776 3 Debian, Linux, Redhat 10 Debian Linux, Linux Kernel, Enterprise Linux and 7 more 2025-03-05 7.8 High
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
CVE-2023-4569 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2025-02-27 5.5 Medium
A memory leak flaw was found in nft_set_catchall_flush in net/netfilter/nf_tables_api.c in the Linux Kernel. This issue may allow a local attacker to cause double-deactivations of catchall elements, which can result in a memory leak.
CVE-2023-6857 6 Apple, Debian, Google and 3 more 12 Macos, Debian Linux, Android and 9 more 2025-02-13 5.3 Medium
When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS). Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-4208 3 Debian, Linux, Redhat 6 Debian Linux, Linux Kernel, Enterprise Linux and 3 more 2025-02-13 7.8 High
A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. When u32_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free. We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81.

A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to achieve local privilege escalation. When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into the new instance of the filter. This causes a problem when updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading to a use-after-free. We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8.
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-2023-0045 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-2023-3863 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2025-02-13 6.4 Medium
