Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.75.60

medium Tenable Cloud Security Plugin ID 472338

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 necessary resources for the signal delivery, preventing the signal from being delivered with siginfo.
This prevents the process from correctly identifying the fault address and handling the error. From the
user-space perspective, applications are unaware that the limit has been reached and that the siginfo is
effectively 'corrupted'. This can lead to unpredictable behavior and crashes, as we observed with java
applications. Fix this by passing override_rlimit into inc_rlimit_get_ucounts() and skip the comparison to
max there if override_rlimit is set. This effectively restores the old behavior. (CVE-2024-50271)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.75.60 or later.
