AZL-100250 CVE-2026-89648 affecting package kernel 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: ceph: cap delegated inode count in cephparsedeleginos cephparsedeleginos decodes interval sets of delegated inode numbers from an MDS create-with-delegation reply. For each set it reads a 64-bit start and a 64-bit len with...

DEBIAN-CVE-2026-89647

In the Linux kernel, the following vulnerability has been resolved: ceph: do not repeat cephtrimdentries if no progress possible cephcapreclaimwork re-queues itself for as long as cephtrimdentries returns -EAGAIN, which happens whenever a lease walk exhausts its nrtoscan budget. This creates a bu...

AZL-100145 CVE-2026-89649 affecting package kernel for versions less than 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: ceph: bound xattr value length in buildxattrs buildxattrs decodes the MDS-supplied xattr blob one attribute at a time. For each attribute it reads a 32-bit name length, advances past the name bytes, reads a 32-bit value length,...

DEBIAN-CVE-2026-89639

In the Linux kernel, the following vulnerability has been resolved: cifs: use cifsinvalidatecache in cifsdotruncate for OTRUNC cifsdotruncate is invoked from cifsopen without irwsem, so it cannot use cifsresizefilelocked to perform a proper fscache cookie resize. Instead, add cifsinvalidatecache...

DEBIAN-CVE-2026-89642

In the Linux kernel, the following vulnerability has been resolved: cifs: call pagecacheisizeextended in cifssetsize when extending cifssetsize calls truncatepagecache but skips pagecacheisizeextended on extension. truncatesetsize shows the correct pattern: isizewriteinode, newsize; if newsize...

AZL-100271 CVE-2026-89617 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate dirty page table on log replay Each DIRPAGEENTRY ends in a pagelcns array whose length is the on-disk lcnsfollow field. checkrstbl validates the table bookkeeping but never checks that this array fits in the...

DEBIAN-CVE-2026-89615

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: bound pagelcns index by the log record The copylcns loop and the redo shorten loop index pagelcns at j + i, where i runs up to the log record's lcnsfollow. That count is checked only against the record's own length, not...

DEBIAN-CVE-2026-89611

In the Linux kernel, the following vulnerability has been resolved: ntfs: validate non-resident attribute offsets ntfsattrupdatemeta shifts the attribute name when converting between non-sparse and sparse attributes. Converting to sparse also adds the compressedsize field before the name and...

DEBIAN-CVE-2026-89614

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the free-cluster bitmap scan to the volume vol-lcnemptybitsperpage is sized from vol-nrclusters at mount, but ntfsclusteralloc bounds its scan of that array by the size of $Bitmap. Those are independent on-disk...

CVE-2026-89602

In the Linux kernel, the following vulnerability has been resolved: erofs: skip sufficiently large global buffers when resizing zerofsgbufnrpages is advanced only after every global buffer has been grown. If a resize fails after some buffers were enlarged, a retry revisits those enlarged buffers...

CVE-2026-89601

In the Linux kernel, the following vulnerability has been resolved: ext2: Fix lost inode updates for ISSYNC inodes ext2setsize and ext2xattrset2 had a construct like: if ISSYNCinode syncinodemetadatainode, 1; else markinodedirtyinode; which leads to lost inode updates for ISSYNC inodes because...

DEBIAN-CVE-2026-89525

In the Linux kernel, the following vulnerability has been resolved: udf: reject VAT indexes equal to the entry count UDF 1.50 virtual partition mapping uses the VAT as an array of physical block mappings. snumentries stores the number of entries in that array, not the highest valid index. The val...
