UBUNTU-CVE-2025-22115

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix block group refcount race in btrfscreatependingblockgroups Block group creation is done in two phases, which results in a slightly unintuitive property: a block group can be allocated/deallocated from after...

SUSE CVE-2022-49174

In the Linux kernel, the following vulnerability has been resolved: ext4: fix ext4mbmarkbb with flexbg with fastcommit In case of flexbg feature which is by default enabled, extents for any given inode might span across blocks from two different block group. ext4mbmarkbb only reads the bufferhead...

AZL-54920 CVE-2024-56672 affecting package kernel for versions less than 6.6.76.1-1

In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: Fix UAF in blkcgunpinonline blkcgunpinonline walks up the blkcg hierarchy putting the online pin. To walk up, it uses blkcgparentblkcg but it was calling that after blkcgdestroyblkgsblkcg which could free the blkcg,...

CVE-2024-42231 btrfs: zoned: fix calc_available_free_space() for zoned mode

In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: fix calcavailablefreespace for zoned mode calcavailablefreespace returns the total size of metadata or system block groups, which can be allocated from unallocated disk space. The logic is wrong on zoned mode in two...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel, which stems from a possible concurrent list addition issue in the btrfs module when adding block groups to retry lists and unus...

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...

SUSE CVE-2016-10208

The ext4fillsuper function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service out-of-bounds read and system crash via a crafted ext4 image...

Design/Logic Flaw

An issue was discovered in the Linux kernel through 4.17.10. There is out-of-bounds access in writeextentbuffer when mounting and operating a crafted btrfs image, because of a lack of verification that each block group has a corresponding chunk at mount time, within btrfsreadblockgroups in...
