CVE-2026-63864

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. The visittailcallinsn function, which is part of the BPF program validation process, failed to check and propagate error return values. This oversight could lead to an unhandled error condition within the kernel,...

CVE-2026-63863

A flaw was found in the Linux kernel's Direct Rendering Manager DRM Graphics Processing Unit Shared Virtual Memory gpusvm component. This vulnerability is caused by an unbalanced lock and unlock operation, which can lead to system instability. An attacker could potentially exploit this to trigger...

CVE-2026-63860

A flaw was found in the Linux kernel's RDMA/core component. This vulnerability arises from the improper handling of Netlink Attribute NLA strings, where attributes evaluated as C-strings do not properly check for a null terminator. A local attacker could potentially provide specially crafted inpu...

CVE-2026-63858

A flaw was found in the Linux kernel's netfilter nftables subsystem. This vulnerability could lead to a denial of service for network filtering operations. The issue occurs because the process of deleting network hooks improperly modifies a protected list, which can disrupt how network...

kernel: crypto: af_alg - zero initialize memory allocated via sock_kmalloc

A flaw was found in the Linux kernel's crypto AFALG subsystem. Memory allocated via sockkmalloc for crypto user API contexts is not zero-initialized, leaving fields with garbage values. Specifically, the 'inflight' variable can contain random data, causing afalgallocareq to spuriously return -EBU...

kernel: Linux kernel: Denial of Service due to memory leak in tpm2_load_cmd

A flaw was found in the Linux kernel's trusted keys subsystem. A local user could exploit a memory leak in the tpm2loadcmd function, which fails to free a temporary memory allocation in certain error scenarios. This memory leak could lead to a system-wide Denial of Service DoS by exhausting...

kernel: ice: fix double-free of tx_buf skb

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

kernel: flex_proportions: make fprop_new_period() hardirq safe

A deadlock vulnerability was found in the Linux kernel's flexible proportions fprop code used for I/O writeback accounting. When a hardirq interrupts the seqcount write section in fpropnewperiod during softirq context, a reader in the hardirq handler can spin indefinitely waiting for the odd...

kernel: xfrm: defensively unhash xfrm_state lists in __xfrm_state_delete

A flaw was found in the Linux kernel's xfrm IPSec framework subsystem. This vulnerability, a use-after-free, occurs when the system incorrectly manages memory related to security policies, specifically during the deletion of xfrmstate lists. An attacker with local access could exploit this flaw b...

kernel: fanotify: fix false positive on permission events

A flaw was found in the Linux kernel's fanotify subsystem. This vulnerability allows for a bypass of permission checks because the fsnotifygetmarksafe function may incorrectly return false for marks on unrelated groups. This could enable an attacker to perform unauthorized actions by circumventin...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from t...

CVE-2026-64018

A flaw was found in the Linux kernel's mana network driver. In Confidential Virtual Machines VMs, a missing bounds check when processing network events can allow a malicious hardware component or a compromised VM to write data outside of an intended memory region. This out-of-bounds access could...

CVE-2026-63882

A flaw was found in the AMD KFD Kernel Fusion Driver component of the Linux kernel. A local user could trigger a null pointer dereference in the svmrangesetattr function by not calling kfdioctlacquirevm before kfdioctlsvm. This could lead to a denial of service...

CVE-2026-63901

A flaw was found in the Linux kernel's digiacceleport USB serial driver. A malicious Universal Serial Bus USB device could report smaller bulk-out buffers than expected. This lack of proper size validation could lead to out-of-bounds memory accesses or slab corruption, potentially causing system...

CVE-2026-64031

A flaw was found in the Linux kernel's erofs filesystem. A race condition exists when processing unaligned compressed extents, which can cause a managed memory page folio to be incorrectly added to the page cache multiple times. This inconsistency in memory management could allow a local attacker...

CVE-2026-63998

A flaw was found in the Linux kernel's ethtool module. When attempting to flash transceiver modules' firmware, a validation failure could cause the ethnlopscomplete function to be skipped. This oversight means that an operation initiated by ethnlopsbegin might not be properly concluded, potential...

CVE-2026-63964

A flaw was found in the Linux kernel's USB Type-C UCSI CCG driver. A local attacker with root privileges can provide a specially crafted firmware image without a required record header. This malformed image can cause a null pointer dereference within the doflash function, leading to a kernel cras...

CVE-2026-63877

A flaw was found in the Linux kernel's serial DZ driver. During the initialization of the first serial port, a null pointer dereference occurs because a pointer to the port's parent device is incorrectly derived from a null value. This vulnerability can lead to a system crash, resulting in a Deni...

CVE-2026-63941

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architecture. This vulnerability allows a guest hypervisor with Virtualization Host Extensions VHE to bypass intended security controls. By manipulating the SVE Control Register ZCREL2 through an untrapped access, a...

CVE-2026-63992

A flaw was found in the Linux kernel's tunnels module. This vulnerability occurs when the iptunnelpmtudcheckicmp function is called without the skb transport header being properly set. An attacker could exploit this condition to trigger an out-of-bound memory access, which may lead to system...
