In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: Avoid address calculations via out of bounds array indexing Before request-channels can be used, request-nchannels must be set. Additionally, address calculations for memory after the "channels" array need to be...

CVE-2024-38559 scsi: qedf: Ensure the copied buf is NUL terminated

In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Ensure the copied buf is NUL terminated Currently, we allocate a count-sized kernel buffer and copy count from userspace to that buffer. Later, we use kstrtouint on this buffer but we don't ensure that the string is...

CVE-2024-38559

CVE-2024-38559: In the Linux kernel, the qedf SCSI path copies a userspace buffer without guaranteeing a NUL terminator, risking an OOB read in kstrtouint. The fix uses memdup_user_nul instead of memdup_user. Affected: kernel SCSI qedf path; Root cause: missing termination of the copied buffer. R...

CVE-2024-38556 net/mlx5: Add a timeout to acquire the command queue semaphore

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Add a timeout to acquire the command queue semaphore Prevent forced completion handling on an entry that has not yet been assigned an index, causing an out of bounds access on idx = -22. Instead of waiting indefinitely...

CVE-2024-38556

CVE-2024-38556 affects the Linux kernel net/mlx5 code. The vulnerability arises from how the command queue semaphore timeout handling can allow an entry to be processed before an index is allocated, risking an out-of-bounds access at idx = -22 if the completion path proceeds without proper synchr...

CVE-2024-38549 drm/mediatek: Add 0 size check to mtk_drm_gem_obj

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Add 0 size check to mtkdrmgemobj Add a check to mtkdrmgeminit if we attempt to allocate a GEM object of 0 bytes. Currently, no such check exists and the kernel will panic if a userspace application attempts to...

In the Linux kernel, the following vulnerability has been resolved: drm: vc4: Fix possible null pointer dereference In vc4hdmiaudioinit ofgetaddress may return NULL which is later dereferenced. Fix this bug by adding NULL check. Found by Linux Verification Center linuxtesting.org with SVACE...

CVE-2024-38543 lib/test_hmm.c: handle src_pfns and dst_pfns allocation failure

In the Linux kernel, the following vulnerability has been resolved: lib/testhmm.c: handle srcpfns and dstpfns allocation failure The kcalloc in dmirrordeviceevictchunk will return null if the physical memory has run out. As a result, if srcpfns or dstpfns is dereferenced, the null pointer...

CVE-2024-38543

CVE-2024-38543 : In the Linux kernel, a vulnerability in lib/test_hmm.c arose from allocation failures for src_pfns/dst_pfns. If kcalloc() returns NULL, dereferencing these pointers could trigger a null pointer dereference, especially as the device could be evicted. Remediation implemented: add a...
