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: exec: Cleanup POSIX timers right after de_thread()

A flaw was found in the Linux kernel. When a multi-threaded program sets up a per-thread timer and executes a new program that subsequently fails during startup, the kernel can free timer memory while it remains referenced in an active queue. A local user could exploit this vulnerability to trigg...

CVE-2026-89778

A flaw was found in the Linux kernel's isofs ISO 9660 file system component, specifically within the zisofs decompression logic. A local attacker could exploit this vulnerability by mounting a specially crafted ISO9660 image. When a compressed file on such an image contains a malformed 'ZF' Rock...

CVE-2026-89965

A flaw was found in the Linux kernel's nvdimm/btt component. This vulnerability arises from insufficient validation of the nfree field in the BTT info block, which is read from the storage medium. A specially crafted or foreign arena with an nfree value below the expected lane count can cause an...

CVE-2026-90414

A flaw was found in the Linux kernel's IB/isert module. A remote attacker, after successful login, could send a specially crafted data packet PDU with a declared length exceeding the actual received data. This could lead to an out-of-bounds read of the receive buffer, potentially causing a system...

CVE-2026-89930

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nested virtualization nVMX component. KVM fails to perform necessary Translation Lookaside Buffer TLB flushes when a nested virtual machine VM entry operation fails. This can lead to an outdated TLB state, potentially allowin...

CVE-2026-89786

A flaw was found in the ext4 filesystem component of the Linux kernel. The ext4readinlinedir function can read a directory entry header beyond the allocated buffer, leading to an out-of-bounds read. A local attacker could exploit this vulnerability by interacting with the filesystem, potentially...

CVE-2026-89783

A flaw was found in the Linux kernel's IPv6 networking component. An error in handling security path depth could allow an out-of-bounds write. A remote attacker could exploit this by sending specially crafted IPv6 packets, leading to a system crash and causing a Denial of Service DoS. Mitigation...

CVE-2026-89779

A flaw was found in the Linux kernel's ntfs3 filesystem driver. This vulnerability allows a local attacker to craft an Extended Attribute EA record with an undersized ef-size value. When processed, this can lead to an out-of-bounds read, resulting in the disclosure of sensitive heap memory to...

CVE-2026-90011

A flaw was found in the Linux kernel's iSCSI target component. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted login payload to an iSCSI portal configured for Challenge-Handshake Authentication Protocol CHAP. This can lead to an out-of-bounds read,...
