CVE-2026-80668

A flaw was found in the Netfilter subsystem of the Linux kernel, specifically within nfconntrackexpect. A race condition exists between the removal of an expectation and an expiring timer, which can allow the system to access a stale pointer. This vulnerability could lead to system instability or...

CVE-2026-80666

A flaw was found in the Linux kernel's Bluetooth Synchronous Connection-Oriented SCO component. A race condition exists in the scosocktimeout function. When a Bluetooth SCO socket is closing while its timer is active, the system attempts to acquire the same lock twice, leading to a deadlock. This...

CVE-2026-80634

A flaw was found in the Linux kernel's netfilter flowtable component. An integer underflow can occur during bridge Virtual Local Area Network VLAN untagging operations. If the numencaps value is zero, a decrement operation can cause it to wrap to 255. This can lead to an out-of-bounds stack read...

CVE-2026-80608

A flaw was found in the Linux kernel. This vulnerability, located in the accel/amdxdna component, is a use-after-free issue. It occurs due to a race condition during device removal when forceiova mode is enabled, where a freed memory region can still be accessed. A local attacker could potentiall...

CVE-2026-80625

A flaw was found in the Linux kernel's RDMA/hns component. During concurrent driver removal and reset operations, bonding resources are incorrectly released and then re-allocated, leading to a memory leak. This memory leak can potentially cause a kernel panic, resulting in a Denial of Service DoS...

CVE-2026-80717

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted SCTP INIT message containing a malformed Adaptation Layer Indication parameter. The vulnerability causes the kernel to read beyond t...

kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

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: ipv6: fix possible UAF in icmpv6_rcv()

A flaw was found in the Linux kernel's IPv6 Internet Protocol version 6 implementation. This vulnerability, a Use-After-Free UAF error, occurs due to incorrect caching of network packet addresses before a memory operation. An attacker could potentially exploit this flaw to cause memory corruption...

kernel: can:bcm: arbitrary kernel code execution leading to escalate privileges

A flaw was found in the Linux kernel in net/can/bcm.c in can: bcm, where an unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation LPE. This allows the attacker to gain root privileges and take full control o...

kernel: bonding: alb: fix UAF in rlb_arp_recv during bond up/down

A flaw was found in the Linux kernel's bonding driver, specifically within the Active-Backup Load Balancing ALB receive path. A local attacker can trigger a Use-After-Free UAF vulnerability in the rlbarprecv function by rapidly bringing a bond interface up and down while receiving Address...

kernel: crypto: qat - validate RSA CRT component lengths

A flaw was found in the Linux kernel's QAT QuickAssist Technology crypto module. This vulnerability occurs in the RSA key parser when handling CRT Chinese Remainder Theorem components. An underflow can happen during a memory copy operation if an RSA CRT component is larger than its allocated...

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: NFSD: fix nfs4_file access extra count in nfsd4_add_rdaccess_to_wrdeleg

A flaw was found in the Linux kernel's Network File System Daemon NFSD. An issue with file access counting in the nfsd4addrdaccesstowrdeleg function can lead to an extra access count for nfs4file objects. This prevents the proper freeing of associated resources when the NFS server service is...

kernel: nfsd: fix posix_acl leak on SETACL decode failure

A flaw was found in the Linux kernel's Network File System Daemon nfsd. This vulnerability occurs during the processing of Access Control List ACL set operations. If a specific decode step fails, a memory leak of a posixacl object occurs. This can lead to resource exhaustion over time, potentiall...

kernel: pNFS: Fix use-after-free in pnfs_update_layout()

A flaw was found in the Linux kernel's parallel Network File System pNFS component. An issue in the pnfsupdatelayout function causes a use-after-free vulnerability due to incorrect ordering of memory management operations. This flaw can be triggered when the system attempts to update a pNFS layou...

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...

kernel: mm/list_lru: drain before clearing xarray entry on reparent

A flaw was found in the Linux kernel's memory cgroup memcg listlru component. A race condition occurs during the reparenting of listlru entries when an xarray entry is cleared before its associated lists are fully reparented. This allows concurrent operations to modify list pointers under differe...

kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...
