CVE-2026-64253

In the Linux kernel, the following vulnerability has been resolved: kernel/fork: clear PFBLOCKTS in copyprocess PFBLOCKTS is only set in blktimegetns when current-plug is non-NULL, and blkfinishplug clears it via blkflushplug before NULLing the plug pointer. copyprocess breaks the invariant by...

CVE-2026-64243 ASoC: codecs: simple-mux: Fix enum control bounds check

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: simple-mux: Fix enum control bounds check simplemuxcontrolput rejects values greater than e-items, but enum control values are zero based. For the two-entry mux used by this driver, valid values are 0 and 1, so valu...

kernel: futex: Drop CLONE_THREAD requirement for private default hash alloc

A flaw was found in the Linux kernel's futex subsystem. The needfutexhashallocatedefault function incorrectly relies on CLONETHREAD semantics, which can lead to non-concurrency issues when memory allocations mm-futexref pcpu allocations are shared across CLONEVM clones, excluding vfork. This can...

USN-8575-3: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8606-1 linux-azure, linux-azure-6.8 vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

Name of the Vulnerable Software and Affected Versions libssh2 versions prior to 1.11.1 Description A missing bounds check in the publickey subsystem allows a malicious SSH server to trigger an arbitrary-length heap out-of-bounds read and the free of an uninitialized pointer. In the libssh2...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...

kernel: Bluetooth: hci_event: Fix UAF in hci_acl_create_conn_sync

A flaw was found in the Linux kernel’s Bluetooth subsystem HCI. Specifically, in the function hciaclcreateconnsync and related path hcilecreateconnsync, a connection object in state BTOPEN that is still pending command submission may be freed prematurely, leading to a use-after-free condition. An...

Astra Linux – Vulnerability in Chromium

The use of after-free in the Network subsystem in Google Chrome before version 149.0.7827.53 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory through a crafted HTML page. Chromium security severity: Low...
