CVE-2024-56672

CVE-2024-56672 affects the Linux kernel blk-cgroup component. The issue is a use-after-free (UAF) in blkcg_unpin_online() where blkcg_parent(blkcg) is read after blkcg_destroy_blkgs(blkcg) could free the blkcg. The fix reads the parent pointer before destroying the blkcg’s blkg’s, preventing UAF....

The vulnerability of the blkcg_init_queue() function in the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the blkcginitqueue function in the Linux operating system’s kernel is related to the lack of memory release after the effective lifespan of the function has ended. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2024-36908 blk-iocost: do not WARN if iocg was already offlined

In the Linux kernel, the following vulnerability has been resolved: blk-iocost: do not WARN if iocg was already offlined In iocgpaydebt, warn is triggered if 'activelist' is empty, which is intended to confirm iocg is active when it has debt. However, warn can be triggered during a blkcg or disk...

CVE-2024-36908

CVE-2024-36908 is a Linux kernel issue in the blk-iocost subsystem. The warning in iocg_pay_debt can be triggered during blkcg or disk removal when iocg_waitq_timer_fn() runs, producing a meaningless warning. The patch adds a guard to skip the warn if the iocg was already offlined, since the iocg...

In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: Reinit blkgiostatset after clearing in blkcgresetstats When blkgalloc is called to allocate a blkcggq structure with the associated blkgiostatset's, there are 2 fields within blkgiostatset that requires proper...

CVE-2024-0443 Kernel: blkio memory leakage due to blkcg and some blkgs are not freed after they are made offline.

A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgrouprstatflush is only called at cssreleaseworkfn, which is called when the blkcg reference count reaches 0. This circula...
