In the Linux kernel, the following vulnerability has been resolved: fs: don't return -EINVAL for successful nested thaw Commit 7366f8b6fc6a "fs: handle freezing from multiple devices" replaced the freezeholders bitmask with per-holder counters to allow nested freezes. In the bitmask version, a th...

kernel: dm cache policy smq: fix missing locks in invalidating cache blocks

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: dm rq: Do not queue the request to blk-mq during DM suspension. DM uses blk-mq's quiesce/unquiesce to stop/start the device mapper queue. However, blk-mq's unquiesce may be triggered by external events, such as changes in the...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: dm: fixed a NULL pointer race issue when completing IO operations. The dmiodecpending call first calls endioacct, then decreases the number of pending DMA operations. However, if a task swaps the DM table at the same time, thi...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In the dmstats function, check for and propagate the allocpercpu failure. Check the return value of allocprecpu, and return an error from dmstatsinit if it fails. Update allocdev to fail if dmstatsinit does. Otherwise, a NULL...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix out-of-bounds access to the dirty bitset when resizing dm-cache checks the dirty bits of the cache blocks to be dropped when shrinking the fast device, but an index bug in bitset iteration causes out-of-bounds acces...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: dmarraycursorend: Fix to prevent releasing a faulty array block twice when using dmarraycursorend. When dmbmreadlock fails due to locking or checksum errors, it releases the faulty block implicitly, leaving an invalid output...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: dm thin: Make getfirstthin use rcu-safe list first function. The documentation in rculist.h explains the absence of listemptyrcu and warns programmers against relying on a sequence of listempty - listfirst in RCU-safe code. This ...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: dm integrity: Memory corruption occurs when tagsize is less than digestsize. It is possible to configure dm-integrity in such a way that the tagsize parameter is smaller than the actual digestsize. In this case, a portion of the...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: dm rq: Fixed a double-free of blkmqtagset when removing a device after table loading fails. When loading a device-mapper table for a request-based mapped device, and the allocation/initialization of the blkmqtagset for the device...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: dm: A NULL pointer dereference occurred in dmsuspend. There is a race condition between the suspension of the dm device and the loading of data into the table, which can lead to a NULL pointer dereference. This issue occurs when...
