CVE-2024-50285 – ksmbd: check outstanding simultaneous SMB operations
https://notcve.org/view.php?id=CVE-2024-50285
19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: ksmbd: check outstanding simultaneous SMB operations If Client send simultaneous SMB operations to ksmbd, It exhausts too much memory through the "ksmbd_work_cache”. It will cause OOM issue. ksmbd has a credit mechanism but it can't handle this problem. This patch add the check if it exceeds max credits to prevent this problem by assuming that one smb request consumes at least one credit. This vulnerability allows remote attackers to create... • https://git.kernel.org/stable/c/0626e6641f6b467447c81dd7678a69c66f7746cf •

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: dm cache: fix flushing uninitialized delayed_work on cache_ctr error An unexpected WARN_ON from flush_work() may occur when cache creation fails, caused by destroying the uninitialized delayed_work waker in the error path of cache_create(). For example, the warning appears on the superblock checksum error.

CVE-2024-50278 – dm cache: fix potential out-of-bounds access on the first resume

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: dm cache: fix potential out-of-bounds access on the first resume Out-of-bounds access occurs if the fast device is expanded unexpectedly before the first-time resume of the cache table. This happens because expanding the fast device requires reloading the cache table for cache_create to allocate new in-core data structures that fit the new size, and the check in cache_preresume is not performed during the first resume, leading to the issue.... • https://git.kernel.org/stable/c/f494a9c6b1b6dd9a9f21bbb75d9210d478eeb498 •

CVE-2024-50276 – net: vertexcom: mse102x: Fix possible double free of TX skb

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: net: vertexcom: mse102x: Fix possible double free of TX skb The scope of the TX skb is wider than just mse102x_tx_frame_spi(), so in case the TX skb room needs to be expanded, we should free the the temporary skb instead of the original skb. Otherwise the original TX skb pointer would be freed again in mse102x_tx_work(), which leads to crashes: Internal error: Oops: 0000000096000004 [#2] PREEMPT SMP CPU: 0 PID: 712 Comm: kworker/0:1 Tainted... • https://git.kernel.org/stable/c/2f207cbf0dd44278af2aa3ff0fc95b0f97cc4e4c •
CVE-2024-50275 – arm64/sve: Discard stale CPU state when handling SVE traps

19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: arm64/sve: Discard stale CPU state when handling SVE traps The logic for handling SVE traps manipulates saved FPSIMD/SVE state incorrectly, and a race with preemption can result in a task having TIF_SVE set and TIF_FOREIGN_FPSTATE clear even though the live CPU state is stale (e.g. with SVE traps enabled). This has been observed to result in warnings from do_sve_acc() where SVE traps are not expected while TIF_SVE is set: | if (test_and_set... • https://git.kernel.org/stable/c/cccb78ce89c45a4414db712be4986edfb92434bd •
