CVE-2026-53122

CVE-2026-53122: In the Linux kernel, the btrfs filesystem can deadlock when flushoncommit is used. A transaction commit and a reflink copying an inline extent to an offset beyond the destination i_size create a cycle: a clone to an EOF offset leads to delalloc flush, which flushes and invalidates...

EUVD-2026-38990

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix deadlock between reflink and transaction commit when using flushoncommit When using the flushoncommit mount option, we can have a deadlock between a transaction commit and a reflink operation that copied an inline exte...

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix deadlock between reflink and transaction commit when using flushoncommit When using the flushoncommit mount option, we can have a deadlock between a transaction commit and a reflink operation that copied an inline exte...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: btrfs: In the send operation, it is necessary to check for inline extents within the rangeisholeinparent function. Before accessing the diskbytenr field of a file extent item, we need to check whether we are dealing with an inlin...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: btrfs: fixed a reservation leak in some error paths when inserting inline extents. If we fail to allocate a path or join a transaction, we return from cowfilerangeInline without freeing the reserved qgroup data, resulting in a...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ext4: Fixed a memory leak in ext4extshiftextents. In ext4extshiftextents, if the extent is NULL during the while loop, the function returns immediately without releasing the path obtained via ext4findextent. This leads to a memor...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ext4: Do not zero the entire extent if EXT4EXTDATAPARTIALVALID1 is true. When allocating initialized blocks from a large unwritten extent, or when splitting an unwritten extent during end I/O and converting it to initialized, the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: btrfs: fixed a deadlock in waitcurrenttrans due to an ignored transaction type When waitcurrenttrans is called during starttransaction, it currently waits for a blocked transaction without considering whether the given transactio...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ext4: Do not cache extents during splitting Caching extents during the splitting process is risky, as it may result in stale extents remaining in the status tree. Moreover, in most cases, the corresponding extent block entries ar...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: btrfs: Do not call BUGON when encountering ENOMEM during the dropping of file extent items within a given range.
