kernel: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. The rmif3amapgpios function incorrectly allocates memory for the gpiokeymap, making it smaller than required. This allows a device reporting a specific gpiocount value to trigger an out-of-bounds read, leading to information...

kernel: nvmet: fix pre-auth out-of-bounds heap read in Discovery Get Log Page

A flaw was found in the Linux kernel's nvmet subsystem. An unauthenticated remote attacker could exploit an out-of-bounds heap read vulnerability in the Discovery Get Log Page function. By sending a specially crafted request with a manipulated offset, an attacker could read sensitive kernel memor...

kernel: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. This vulnerability occurs because the driver incorrectly allocates memory for a keymap, leading to an out-of-bounds memory access. A local user with access to a specially crafted input device could exploit this to read or write t...

K000163099: Linux kernel vulnerability CVE-2026-53253

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and...

kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

kernel: net: atm: fix crash due to unvalidated vcc pointer in sigd_send()

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM networking component. A local attacker, by acting as a malicious signaling daemon, could send a specially crafted message containing an unvalidated pointer. This unvalidated pointer would be directly used by the kernel, leading...

kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels

A flaw was found in the Linux kernel's IPv6 networking implementation, specifically within the seg6 and rpl lwtunnels. A race condition can occur when handling destination cache entries, where a NOREF no reference destination object is used after it has been freed. This use-after-free vulnerabili...

kernel: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath

A flaw was found in the Linux kernel's CIFS Common Internet File System client. When the cifssanitizeprepath function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-boun...
