kernel: dm cache policy smq: fix missing locks in invalidating cache blocks

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

kernel: ipv6: validate extension header length before copying to cmsg

A flaw was found in the Linux kernel's IPv6 networking stack. An unprivileged local user could exploit a vulnerability in how IPv6 extension header lengths are handled. By manipulating these headers using nftables, an attacker can trigger an out-of-bounds read, leading to information disclosure...

kernel: blk-cgroup: fix UAF in __blkcg_rstat_flush()

A flaw was found in the Linux kernel's block input/output control group blk-cgroup component. This vulnerability, a Use-After-Free UAF, occurs when multiple block control groups are released at the same time. A race condition allows one group to remove another's entries while it is still in use,...

kernel: ipv6: exthdrs: refresh nh after handling HAO option

A flaw was found in the Linux kernel's IPv6 extension header processing. When processing the Home Address Option HAO, the cached network header pointer may become invalid if the packet's memory is reallocated. This can lead to incorrect parsing of subsequent IPv6 Type-Length-Value TLV options,...

kernel: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show()

A flaw was found in the Linux kernel's SCSI target subsystem. This vulnerability, a buffer overflow, occurs in the tgptgpmembersshow function when processing long iSCSI IQN names. An attacker could potentially exploit this by providing a specially crafted input, leading to the disclosure of...

CVE-2026-98435

A flaw was found in the Linux kernel's Altera EDAC Error Detection and Correction driver. Device-managed interrupt requests and resource groups in the altrportbsetup function were improperly associated with a temporary per-port device structure rather than the parent device. A local privileged us...

CVE-2026-98434

A flaw was found in the Linux kernel. Due to a missing range validation check in the sysctl subsystem, configured minimum and maximum limits were not enforced during specific millisecond-to-jiffies conversions. A local user with permission to modify kernel parameters could provide out-of-bounds...

CVE-2026-98433

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine subsystem for PowerPC architectures. When handling secure virtual machines, a failure during secure memory paging fails to release allocated device memory and internal metadata. A local user can exploit this vulnerability by...
