CVE-2023-52900

A vulnerability was found in the Linux kernel's nilfs2 file system where improper sanitization checks can result in a general protection fault caused by how the nilfsbtreeinsert function interprets a return value -ENOENT from the nilfsbtreegetblock function. This return value is used to indicate...

CVE-2023-52896

A flaw was found in the Linux kernel’s btrfs module. A race condition can occur when one task tries to start the quota rescan worker while another tries to disable quotas. This issue can cause a NULL pointer dereference and result in a denial of service...
