Linux Distros Unpatched Vulnerability : CVE-2024-56610
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - kcsan: Turn reportfilterlistlock into a rawspinlock Ran Xiaokai reports that with a KCSAN-enabled PREEMPTRT kernel, we can see splats like: | BUG: sleeping...
CVE-2022-49443
In the Linux kernel, the following vulnerability has been resolved: list: fix a data-race around ep-rdllist eppoll first calls epeventsavailable with no lock held and checks if ep-rdllist is empty by listemptycareful, which reads rdllist-prev. Thus all accesses to it need some protection to avoid...
CVE-2022-49420
In the Linux kernel, the following vulnerability has been resolved: net: annotate races around sk-skbounddevif UDP sendmsg is lockless, and reads sk-skbounddevif while this field can be changed by another thread. Adds minimal annotations to avoid KCSAN splats for UDP. Following patches will add...
UBUNTU-CVE-2022-49344
In the Linux kernel, the following vulnerability has been resolved: afunix: Fix a data-race in unixdgrampeerwakeme. unixdgrampoll calls unixdgrampeerwakeme without other's lock held and check if its receive queue is full. Here we need to use unixrecvqfulllockless instead of unixrecvqfull, otherwi...

CVE-2022-49344
The CVE-2022-49344 issue is a Linux kernel data race in af_unix between unix_dgram_poll() and unix_dgram_peer_wake_me(): the receive-queue fullness check was done without holding the peer’s lock. The fix uses unix_recvq_full_lockless() instead of unix_recvq_full(), addressing a KCSAN-reported rac...

CVE-2024-56610
CVE-2024-56610 is a Linux kernel issue where KCSAN’s report_filterlist_lock, originally protected by a non-raw spinlock, could lead to a data race on PREEMPT_RT. The patch converts the filter list lock to raw_spinlock to avoid sleeping in atomic contexts on RT kernels; it notes that memory alloca...
