CVE-2026-98923

A flaw was found in the Linux kernel. A local user can cause a Denial of Service DoS by triggering an unexpected kernel warning on ARM64 systems. By establishing a restricted memory mapping and reading process details through the /proc interface, the kernel incorrectly flags valid user protection...

CVE-2026-98926

A flaw was found in the Linux kernel's AMD display driver. During Display Power Management Signaling DPMS sequences, the driver attempts to access a display sink pointer without verifying whether it is null. A local user could exploit this flaw during display power state transitions, triggering a...

CVE-2026-98931

A flaw was found in the Linux kernel's Memory Technology Device MTD SPI-NAND driver. When probing a flash memory device configured without an Error Correction Code ECC engine, the driver attempts to access an uninitialized pointer. A local user could exploit this flaw to crash the system, resulti...

CVE-2026-98921

A flaw was found in the Linux kernel's OverlayFS subsystem. When debug logging is enabled, a directory creation operation can trigger a use-after-free condition by referencing a directory entry that has already been released by the virtual file system. A local user could exploit this flaw to cras...

CVE-2026-98942

A flaw was found in the Linux kernel's schedext extensible scheduler subsystem. Due to a race condition, internal core-ID mapping tables were exposed before being fully initialized and were modified without adequate synchronization. A local attacker could exploit this timing issue during schedule...

kernel: procfs: fix missing RCU protection when reading real_parent in do_task_stat()

A flaw was found in the Linux kernel's procfs component. When reading /proc/pid/stat, the dotaskstat function accesses task-realparent without proper Read-Copy-Update RCU protection. This missing protection creates a race condition, which can lead to a Use-After-Free UAF vulnerability. A local...

kernel: ALSA: usx2y: bound the hwdep mmap fault offset

A flaw was found in the Advanced Linux Sound Architecture ALSA usx2y driver in the Linux kernel. A local attacker, by opening the hwdep node of an attached US-X2Y device, could exploit an unbounded memory mapping mmap fault offset. This allows read-write access to arbitrary kernel memory,...

kernel: ALSA: 6fire: fix use-after-free on disconnect

A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...

kernel: net: bridge: use a stable FDB dst snapshot in RCU readers

A flaw was found in the Linux kernel. Inconsistent handling of local Forwarding Database FDB entries in the bridge networking component's RCU Read-Copy-Update readers can lead to a null-pointer dereference. A local attacker could exploit this by triggering a concurrent update to an FDB entry,...

kernel: mac802154: llsec: add skb_cow_data() before in-place crypto

A flaw was found in the Linux kernel's mac802154 IEEE 802.15.4 MAC security component. This vulnerability allows for data corruption and potential kernel crashes when cryptographic transformations are performed on shared network packet data without proper isolation. A remote attacker could exploi...

kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests

A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...

Important: Red Hat Security Advisory: kernel security update

An update for kernel is now available for Red Hat Enterprise Linux 8.8 Update Services for SAP Solutions and Red Hat Enterprise Linux 8.8 Telecommunications Update Service. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring Syst...

kernel: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset

A flaw was found in the Linux kernel's qla2xxx SCSI driver. This vulnerability occurs when commands sent to the firmware FW are not properly cleared after a chip reset. A local attacker could exploit a race condition during direct memory access DMA unmapping, leading to a kernel panic. This can...

kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read

A flaw was found in the Linux kernel's scsi: qla2xxx driver. A remote attacker, by sending a specially crafted Fibre Channel Protocol FCP response, could cause an integer underflow. This underflow leads to an out-of-bounds read when handling sense data, potentially disclosing sensitive memory...

kernel: crypto: af_alg - Cap AEAD AD length to 0x80000000

A flaw was found in the Linux kernel's afalg cryptography module. This vulnerability involves an arithmetic overflow when processing associated data lengths during the transmit buffer size check. A remote attacker could exploit this flaw by providing a specially crafted associated data length,...

kernel: selinux: check connect-related permissions on TCP Fast Open

A flaw was found in the Linux kernel's Security-Enhanced Linux SELinux module. When using TCP Fast Open, SELinux failed to properly check connect-related permissions. This oversight could allow a local attacker to bypass SELinux network access controls, potentially enabling unauthorized network...

CVE-2026-118593

A flaw was found in Red Hat Enterprise Linux 9 kernel builds. An incomplete backport of the CVE-2026-46099 fix in RHEL 9.6 through 9.10 left a localbh imbalance in seg6inputcore, where the drop path returns with bottom halves still disabled. This can lead to softirq starvation and denial of servi...

CVE-2026-118593

A flaw exists in Red Hat Enterprise Linux 9 kernel builds (specifically versions 9.6 through 9.10) due to an incomplete backport of the CVE-2026-46099 fix. The vulnerability is caused by a local_bh imbalance in the seg6_input_core() function, where the drop path returns while bottom halves remain...
