https://notcve.org/view.php?id=CVE-2024-50014
In the Linux kernel, the following vulnerability has been resolved: ext4: fix access to uninitialised lock in fc replay path The following kernel trace can be triggered with fstest generic/629 when executed against a filesystem with fast-commit feature enabled: INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use? turning off the locking correctness validator.

https://notcve.org/view.php?id=CVE-2024-50012
In the Linux kernel, the following vulnerability has been resolved: cpufreq: Avoid a bad reference count on CPU node In the parse_perf_domain function, if the call to of_parse_phandle_with_args returns an error, then the reference to the CPU device node that was acquired at the start of the function would not be properly decremented. Address this by declaring the variable with the __free(device_node) cleanup attribute. • https://git.kernel.org/stable/c/0f41f383b5a61a2bf6429a449ebba7fb08179d81 https://git.kernel.org/stable/c/77f88b17387a017416babf1e6488fa17682287e2 https://git.kernel.org/stable/c/47cb1d9278f179df8250304ec41009e3e836a926 https://git.kernel.org/stable/c/c0f02536fffbbec71aced36d52a765f8c4493dc2 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-50010 – exec: don't WARN for racy path_noexec check
https://notcve.org/view.php?id=CVE-2024-50010
In the Linux kernel, the following vulnerability has been resolved: exec: don't WARN for racy path_noexec check Both i_mode and noexec checks wrapped in WARN_ON stem from an artifact of the previous implementation. They used to legitimately check for the condition, but that got moved up in two commits: 633fb6ac3980 ("exec: move S_ISREG() check earlier") 0fd338b2d2cd ("exec: move path_noexec() check earlier") Instead of being removed said checks are WARN_ON'ed instead, which has some debug value. However, the spurious path_noexec check is racy, resulting in unwarranted warnings should someone race with setting the noexec flag. One can note there is more to perm-checking whether execve is allowed and none of the conditions are guaranteed to still hold after they were tested for. Additionally this does not validate whether the code path did any perm checking to begin with -- it will pass if the inode happens to be regular. Keep the redundant path_noexec() check even though it's mindless nonsense checking for guarantee that isn't given so drop the WARN. Reword the commentary and do small tidy ups while here.
