kernel: net: fix out-of-bounds access in ops_init

An out-of-bounds memory access flaw was found in the Linux kernel’s networking subsystem in how a local user triggers a complex race condition. This flaw allows a local user to crash or potentially escalate their privileges on the system...

kernel: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER

A deadlock flaw was found in the Linux kernel’s pinctrl subsystem. This flaw allows a local user to crash the system...

kernel: tty: Fix out-of-bound vmalloc access in imageblit

A vulnerability was found in the Linux kernel's tty subsystem within the imageblit function when a userspace program performs an ioctl operation with the FBIOPUTVSCREENINFO command, passing a fbvarscreeninfo structure with limited fields. If the structure’s values remain unchanged from a previous...

kernel: ACPI: fix NULL pointer dereference

A vulnerability was found in the Linux kernel’s ACPI subsystem, where the acpidevput function could attempt to operate on a NULL pointer, leads to a system crash due to a NULL pointer dereference, causing instability when managing ACPI devices...

kernel: net: fix possible store tearing in neigh_periodic_work()

A flaw was found in the Linux kernel that allows for potential store tearing within the neighperiodicwork function, meaning a write operation on a value is not protected properly and could result in inconsistencies if another process or thread reads from that value before the operation is complet...

kernel: fbmem: Do not delete the mode that is still in use

A vulnerability was found in the Linux kernel's fbmem subsystem. This issue arises when the system attempts to delete a video mode that is still in use, leading to potential use-after-free errors. This improper handling can result in system crashes or undefined behavior when accessing freed memor...

kernel: tty: n_gsm: fix possible out-of-bounds in gsm0_receive()

A vulnerability was found in the Linux kernel's ngsm driver, affecting the tty subsystem. It occurs when switching between basic and advanced option modes in GSM multiplexing, leading to potential out-of-bounds memory writes. This happens because certain state variables, like gsm-len and gsm-stat...

kernel: net: fix possible store tearing in neigh_periodic_work()

A flaw was found in the Linux kernel that allows for potential store tearing within the neighperiodicwork function, meaning a write operation on a value is not protected properly and could result in inconsistencies if another process or thread reads from that value before the operation is complet...

kernel: net/sched: act_api: fix possible infinite loop in tcf_idr_check_alloc()

A vulnerability was found in the Linux kernel's networking subsystem in the actapi implementation within the tcfidrcheckalloc function, which lead to a possible infinite loop when multiple actions with the same index are added, causing the second request to block indefinitely while holding the...

kernel: wifi: cfg80211: restrict NL80211_ATTR_TXQ_QUANTUM values

A vulnerability was found in the cfg80211 component in the Linux kernel, where a lack of proper range validation applied to the NL80211ATTRTXQQUANTUM can lead to a scenario where the userspace passes an extremely high value that the kernel is not designed to handle efficiently ex. 2^31. This can...

kernel: ACPI: extlog: fix NULL pointer dereference check

REJECTED CVE A NULL pointer dereference issue was identified in the Linux kernel within the ACPI subsystem's extlog module. In the extlogexit function, the extlogl1addr pointer was dereferenced before verifying if it was NULL, potentially causing system instability or crashes during the cleanup...

kernel: fbmem: Do not delete the mode that is still in use

A vulnerability was found in the Linux kernel's fbmem subsystem. This issue arises when the system attempts to delete a video mode that is still in use, leading to potential use-after-free errors. This improper handling can result in system crashes or undefined behavior when accessing freed memor...

kernel: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER

A deadlock flaw was found in the Linux kernel’s pinctrl subsystem. This flaw allows a local user to crash the system...

kernel: hwmon: (mlxreg-fan) Return non-zero value when fan current state is enforced from sysfs

A vulnerability was found in the Linux kernel's hwmon subsystem, specifically in the mlxreg-fan driver. The issue arises when the driver’s sysfs interface for controlling fan speed does not properly handle cases where the requested minimum fan speed exceeds the maximum allowable value. When the...

USN-7021-2: Linux kernel vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - GPU drivers; - BTRFS file system; - F2FS file system; - GFS2 file system; - BPF subsystem; - Netfilter; - RxRPC...

USN-7029-1: Linux kernel vulnerabilities

Chenyuan Yang discovered that the CEC driver driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2024-23848 It was discovered that the JFS file system contained an...

USN-7028-1: Linux kernel vulnerabilities

It was discovered that the JFS file system contained an out-of-bounds read vulnerability when printing xattr debug information. A local attacker could use this to cause a denial of service system crash. Several security issues were discovered in the Linux kernel. An attacker could possibly use...
