CVE-2024-50271 – signal: restore the override_rlimit logic
https://notcve.org/view.php?id=CVE-2024-50271
19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: signal: restore the override_rlimit logic Prior to commit d64696905554 ("Reimplement RLIMIT_SIGPENDING on top of ucounts") UCOUNT_RLIMIT_SIGPENDING rlimit was not enforced for a class of signals. However now it's enforced unconditionally, even if override_rlimit is set. This behavior change caused production issues. For example, if the limit is reached and a process receives a SIGSEGV signal, sigqueue_alloc fails to allocate the nece... • https://git.kernel.org/stable/c/d64696905554e919321e31afc210606653b8f6a4 •
CVE-2024-50270 – mm/damon/core: avoid overflow in damon_feed_loop_next_input()
https://notcve.org/view.php?id=CVE-2024-50270
19 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: avoid overflow in damon_feed_loop_next_input() damon_feed_loop_next_input() is inefficient and fragile to overflows. Specifically, 'score_goal_diff_bp' calculation can overflow when 'score' is high. The calculation is actually unnecessary at all because 'goal' is a constant of value 10,000. Calculation of 'compensation' is again fragile to overflow. Final calculation of return value for under-achiving case is again frag... • https://git.kernel.org/stable/c/9294a037c01564786abb15436529fae3863268a2 •

11 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: fork: only invoke khugepaged, ksm hooks if no error There is no reason to invoke these hooks early against an mm that is in an incomplete state. The change in commit d24062914837 ("fork: use __mt_dup() to duplicate maple tree in dup_mmap()") makes this more pertinent as we may be in a state where entries in the maple tree are not yet consistent. Their placement early in dup_mmap() only appears to have been meaningful for early error che... • https://packetstorm.news/files/id/183019 •
