EUVD-2026-32298

In the Linux kernel, the following vulnerability has been resolved: ext2: reject inodes with zero inlink and valid mode in ext2iget ext2iget already rejects inodes with inlink == 0 when imode is zero or idtime is set, treating them as deleted. However, the case of inlink == 0 with a non-zero mode...

CVE-2026-46002

Summary (CVE-2026-46002) The Linux kernel ext2 inode handling is fixed to catch a corner case where an inode with i_nlink == 0 and a non-zero i_mode could slip through if i_dtime is 0, allowing a crafted image to trigger WARN_ON in drop_nlink() via ext2_unlink/rename/rmdir. The patch extends the ...

CVE-2026-1933 Samba: missing access check on reparse point operations

A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-onl...

CVE-2026-45984 gfs2: Fix use-after-free in iomap inline data write path

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix use-after-free in iomap inline data write path The inline data buffer head dibh is being released prematurely in gfs2iomapbegin via releasemetapath while iomap-inlinedata still points to dibh-bdata. This causes a...

CVE-2026-45983

In CVE-2026-45983, the Linux kernel NFS server (nfsd) vulnerability stems from idmap lookup upcalls during v4 request decoding: if upcall responses are delayed beyond the time limit, cache_check() postpones the request and it gets dropped, causing NFSD4_SLOT_INUSE to block subsequent SEQUENCE ope...

CVE-2026-45943 erofs: fix inline data read failure for ztailpacking pclusters

In the Linux kernel, the following vulnerability has been resolved: erofs: fix inline data read failure for ztailpacking pclusters Compressed folios for ztailpacking pclusters must be valid before adding these pclusters to I/O chains. Otherwise, zerofsdecompresspcluster may assume they are alread...

CVE-2026-45942

Summary of CVE-2026-45942 : A race condition in the Linux kernel ext4 bitmap handling enables inconsistent bitmap reporting due to concurrent page migration and bitmap modification in the load_buddy path. The root cause is that the fast load_buddy path only increments the folio refcount and can o...
