CVE-2025-21832

In the Linux kernel, the following vulnerability has been resolved: block: don't revert iter for -EIOCBQUEUED blkdevreaditer has a few odd checks, like gating the position and count adjustment on whether or not the result is bigger-than-or-equal to zero where bigger than makes more sense, and not...

CVE-2024-46748

In the Linux kernel, the following vulnerability has been resolved: cachefiles: Set the max subreq size for cache writes to MAXRWCOUNT Set the maximum size of a subrequest that writes to cachefiles to be MAXRWCOUNT so that we don't overrun the maximum write we can make to the backing filesystem...

CVE-2024-46748

The CVE-2024-46748 entry concerns the Linux kernel cachefiles subsystem. It fixes a write-size issue by setting the maximum subrequest size for cache writes to MAX_RW_COUNT, preventing overruns on backing filesystems. Connected docs confirm the fix applies to Linux kernel versions using this code...
