In the Linux kernel, the following vulnerability has been resolved: irqchip/mchp-eic: The error code in mchpeicdomainalloc has been fixed. If irqdomaintranslatetwocell sets “hwirq” to = MCHPEICNIRQ 2, it may lead to an out-of-bounds access. The code checks for invalid values, but does not set the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire-motu – added a bounds check in the putuser loop for DSP events. In the DSP event handling code, the putuser loop copies event data. When the user buffer size is not aligned to 4 bytes, it may overwrite data beyond...

In the Linux kernel, the following vulnerability has been resolved: mptcp: avoid deadlock on fallback while reinjecting Jakub reported a MPTCP deadlock at the time of fallback: WARNING: possible recursive locking detected 6.18.0-rc7-virtme 1 Not tainted -------------------------------------------...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: In the bpf and arm64 architectures, there is a vulnerability where forcing an 8-byte alignment for the JIT buffer can prevent atomic tearing. The struct bpfplt structure contains a u64 target field. Currently, the BPF JIT allocat...

In the Linux kernel, the following vulnerabilities have been resolved: ntfs3: Fixed an issue where an uninitialized buffer allocated by getname was used. Fixed uninitialized errors that occurred after the buffer was allocated to ‘de’; by initializing the buffer with zeros. This fix was discovered...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: Bluetooth: hcisync: fixed a race condition in hcicmdsyncdequeueonce. The function hcicmdsyncdequeueonce performs a lookup and then cancels the entry under two separate lock sections. Meanwhile, hcicmdsyncwork can also delete t...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: ath12k – Fix for the dmafreecoherent pointer. dmaalloccoherent allocates a DMA-mapped buffer and stores the addresses in XXXunaligned fields. These addresses should be reused when freeing the buffer, rather than using th...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: NFS: Fixed a deadlock involving nfsreleasefolio Wang Zhaolong reported a deadlock involving NFSv4.1 state recovery, waiting on kthreadd, which attempts to reclaim memory by calling nfsreleasefolio. The latter cannot proceed due t...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipv4: A reference count leak was fixed when using error routes with nexthop objects. When a nexthop object is deleted, it is marked as “dead”, and then fibtableFlush is called to flush all routes that use the dead nexthop. The...

In the Linux kernel, the following vulnerability has been resolved: PCI: cadence: Check for the existence of cdnspcie::ops before using it. cdnspcie::ops may not be populated by all Cadence glue drivers. This is true for the upcoming Sophgo platform, which does not set ops. Therefore, add a check...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: net/handshake: The function handshakereqsubmit replaces sk-skdestruct, but it never restores it when submission fails before the request is hashed. As a result, handshakeskdestruct returns early, and the original destructor never...
