CVE-2026-80630

A flaw was found in the Linux kernel's fqcodel Fair Queueing Controlled Delay network scheduler. When fqcodel drops packets during a peek operation, it incorrectly calls qdisctreereducebacklog before restoring the queue length. This can lead to the parent's class being mistakenly deactivated,...

CVE-2026-80705

A flaw was found in the Linux kernel's drm/amd/display component. This vulnerability arises from an insufficient check during the allocation of a 'phantom plane' within the display driver. If the allocation fails and this failure is not properly handled, it can lead to a system crash, resulting i...

CVE-2026-80616

A flaw was found in the Linux kernel's ieee802154 component. An unnecessary warning message WARNON can be triggered when memory allocation fails in the cfg802154switchnetns function. This can lead to diagnostic messages being logged due to deliberate fault injections, but does not pose a direct...

kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...

Important: Red Hat Security Advisory: kernel security update

An update for kernel is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...

CVE-2026-80719

A flaw was found in the Linux kernel's Multi-Generational Least Recently Used MGLRU page table walker. When memory cgroup memcg reparenting occurs concurrently with page table walks, stale batch updates can lead to an underestimation of the number of pages. This can prevent the kernel from...

CVE-2026-80658

A flaw was found in the drm/rockchip: dwdp component of the Linux kernel. This vulnerability occurs when the platform driver's remove callback attempts to access driver data before it has been properly initialized by the bind callback. This can lead to a null pointer dereference, potentially...

CVE-2026-80649

A flaw was found in the Linux kernel's System Control and Management Interface SCMI power management. The scmipowernameget function fails to validate the domain number provided by an external caller. This oversight can lead to an out-of-bounds access, potentially allowing an attacker to read or...

CVE-2026-80644

A flaw was found in ocfs2, a component of the Linux kernel. A local attacker could exploit this vulnerability by providing a specially crafted OCFS2 image. When this fuzzed image is mounted, it can corrupt the journal dinode. This corruption leads to a kernel crash, resulting in a Denial of Servi...

CVE-2026-80613

A flaw was found in the Linux kernel's veth component. An error in the rollback mechanism during XDP eXpress Data Path enablement can lead to a Networked Asynchronous Packet Interface NAPI structure not being properly deallocated. This results in a Use-After-Free UAF vulnerability, where freed...

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...

CVE-2026-80624

A flaw was found in the Linux kernel's mfd: cs42l43 component. This vulnerability occurs because the system does not properly verify that the received firmware's size is larger than its header. An attacker could exploit this by providing a malformed firmware, leading to an out-of-bounds memory...

CVE-2026-80617

A flaw was found in the Linux kernel's net: airoha driver. An incorrect memory allocation size for the foechecktime array can lead to a heap buffer overflow. When the airohappefoeverifyentry function is called with a specific hash value, it writes beyond the intended buffer. This out-of-bounds...

CVE-2026-80687

A flaw was found in the Linux kernel's iommufd/viommu component. An error in the iommufdvdeviceallocioctl function's error handling path can lead to a lock being held indefinitely. This can cause a deadlock, preventing further virtual device vDEVICE operations and resulting in a Denial of Service...

CVE-2026-80611

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI processor idle functionality. When kernel tracing features, such as function tracing or Kprobes, are enabled, entering a Low Power Idle LPI state can trigger a Read-Copy Update RCU warning. This occurs because...

CVE-2026-80607

A flaw was found in the Linux kernel's tracing/probes component. A local user could trigger a kernel warning WARNONONCE by adding a kprobe event based on a raw address with a BTF BPF Type Format parameter. This could lead to minor information disclosure through kernel log messages...

CVE-2026-80605

A flaw was found in the Linux kernel. An integer overflow in the picolcdsendandwait function within the Human Interface Device HID picolcd driver can occur when a signed loop counter overflows. This can lead to an incorrect condition evaluation, resulting in a NULL pointer dereference. This...

CVE-2026-80714

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When a synced connection is established, it can incorrectly inherit a "one-packet" flag from its destination. This misconfiguration causes the connection's expiry process to mishandle its cleanup, leaving behind stale memory...

CVE-2026-80683

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. A local attacker or a nearby malicious Bluetooth device could trigger a race condition during the disconnection process, specifically when the scoconndel function attempts to release a...

CVE-2026-80690

A flaw was found in the Linux kernel's SCSI Universal Flash Storage UFS core. When the ufshcdallochost function fails to initialize the hba-rpmbs list, it can lead to a null pointer dereference during device teardown. This vulnerability could allow a local attacker to cause a system crash,...
