CVE-2026-80881 ocfs2: fix buffer head management in ocfs2_read_blocks()

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix buffer head management in ocfs2readblocks In ocfs2readblocks, caller should't assume that buffer head returned by 'sbgetblk' is exclusively owned and so 'putbh' always drops bcount from 1 to 0. If it is not so, buffer...

CVE-2026-80878

CVE-2026-80878 is a resource leak in the Linux kernel's AFS (Andrew File System) module. The function afs_lookup_volume_rcu() fails to release a dying volume when the preceding afs_try_get_volume() call fails, resulting in a leak of an ungot volume . The fix is provided in kernel patches (commits...

In the Linux kernel, the following vulnerability has been resolved: afs: Fix vllist leak Fix a leak of the new vllist in afsupdatecell in the event that it is an empty list nrservers == 0, in which case the old list isn't displaced unless the old list is also empty...

CVE-2026-80877

CVE-2026-80877 is a memory leak in the Linux kernel's AFS (Andrew File System) module. The bug is in afs_update_cell() : when the new server list is empty (nr_servers == 0), the newly allocated vllist is never freed because the old list is only displaced if it is also empty. Each such event leaks...
