CVE-2024-41032

CVE-2024-41032 affects the Linux kernel and has been resolved. The issue occurs on systems where cpu_possible_mask has gaps between set CPUs (e.g., SPARC). In this scenario, addr_to_vb_xa() can return a hash index that targets a non-existent and uninitialized per-CPU area accessed via per_cpu() m...

CVE-2024-41084: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: cxl/region: Avoid null pointer dereference in region lookup cxldpatoregion looks up a region based on a memdev and DPA. It wrongly assumes an endpoint found mapping the DPA is also of a fully assembled region. When not true it...

CVE-2024-41083: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix netfspagemkwrite to check folio-mapping is valid Fix netfspagemkwrite to check that folio-mapping is valid once it has taken the folio lock as filemappagemkwrite does. Without this, generic/247 occasionally oopses with...

CVE-2024-41077: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: nullblk: fix validation of block size Block size should be between 512 and PAGESIZE and be a power of 2. The current check does not validate this, so update the check. Without this patch, nullblk would Oops due to a null pointer...

CVE-2024-41032: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: mm: vmalloc: check if a hash-index is in cpupossiblemask The problem is that there are systems where cpupossiblemask has gaps between set CPUs, for example SPARC. In this scenario addrtovbxa hash function can return an index whic...

CVE-2024-42078: Improper Initialization

In the Linux kernel, the following vulnerability has been resolved: nfsd: initialise nfsdinfo.mutex early. nfsdinfo.mutex can be dereferenced by svcpoolstatsstart immediately after the new netns is created. Currently this can trigger an oops. Move the initialisation earlier before it can possibly...

CVE-2022-48816

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: lock against -sock changing during sysfs read -sock can be set to NULL asynchronously unless -recvmutex is held. So it is important to hold that mutex. Otherwise a sysfs read can trigger an oops. Commit 17f09d3f619a...

CVE-2024-40906

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Always stop health timer during driver removal Currently, if teardownhca fails to execute during driver removal, mlx5 does not stop the health timer. Afterwards, mlx5 continue with driver teardown. This may lead to a UA...
