CVE-2022-48659

CVE-2022-48659 is a Linux kernel issue localized to mm/slub where kmalloc() can fail with an OOM, and the fix ensures create_unique_id() returns a proper errno instead of triggering BUG_ON(). The result is a kernel BUG at mm/slub.c:5893 in the failing path, with the stack showing sysfs_slab_add →...
