UBUNTU-CVE-2024-42078

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...

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...

DEBIAN-CVE-2024-41032

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-2024-41032

CVE-2024-41032: Linux kernel vulnerability in vmalloc hash indexing. Systems where cpu_possible_mask has gaps (e.g., SPARC) could cause addr_to_vb_xa() to hash to a non-existent CPU, accessing an uninitialized per-CPU area and triggering an oops. The per-CPU vmap_block_queue also treated cpu_poss...

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...
