kernel: ipv4: validate checksum_start before completing checksum

A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during...

Vulnerability Details CVEID:CVE-2026-59296 DESCRIPTION: Using untrusted, non-normalized input as-is for metrics data such as metric names, tag keys, or tag values is a dangerous antipattern that general-purpose...

Security update for the Linux Kernel (Live Patch 26 for SUSE Linux Enterprise 15 SP6)

This update for the SUSE Linux Enterprise Kernel 6.4.0-150600.23.112 fixes various security issues: The following security issues were fixed: CVE-2026-53131: netfilter: require Ethernet MAC header before using ethhdr bsc1269775. CVE-2026-63794: KVM: SVM: Fix page overflow in sevdbgcrypt for ENCRY...

kernel: ALSA: hda/cs35l41: Fix firmware load work teardown

A flaw was found in the Linux kernel's ALSA sound driver for the cs35l41 component. This vulnerability occurs because the driver fails to properly remove controls and cancel firmware load work during component unbinding or device removal, especially when firmware autostart is disabled. This can...

kernel: netlabel: Fix NULL pointer exception caused by CALIPSO on IPv4 sockets

In the Linux kernel, the following vulnerability has been resolved: netlabel: Fix NULL pointer exception caused by CALIPSO on IPv4 sockets When calling netlblconnsetattr, addr-safamily is used to determine the function behavior. If sk is an IPv4 socket, but the connect function is called with an...

kernel: ovl: check access to copy_file_range source with src mounter creds

A flaw was found in the Linux kernel's overlayfs component. When copying files across different overlay filesystems, the system incorrectly checked read permissions using the destination filesystem's credentials instead of the source's. This oversight could allow an unauthorized user to read file...

kernel: xfs: fix exchange-range reflink flag clearing issue with INO1_WRITTEN

A flaw was found in the Linux kernel's XFS filesystem. When performing file range exchanges with the XFSEXCHMAPSINO1WRITTEN flag set, the reflink flag can be prematurely cleared from an inode that still manages shared written data. This can lead to data corruption between files that share data...

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

An update for kernel is now available for Red Hat Enterprise Linux 9. 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 th...

kernel: xfs: bounds-check buffer log item's dirty bitmap

A flaw was found in the Linux kernel's XFS filesystem. A local attacker, by mounting a specially crafted XFS image, could trigger an out-of-bounds write during log recovery. This vulnerability allows for kernel heap corruption, which could lead to a denial of service or potentially arbitrary code...

kernel: calipso: Don't call calipso functions for AF_INET sk.

In the Linux kernel, the following vulnerability has been resolved: calipso: Don't call calipso functions for AFINET sk. syzkaller reported a null-ptr-deref in txoptget. 0 The offset 0x70 was of struct ipv6txoptions in struct ipv6pinfo, so struct ipv6pinfo was NULL there. However, this never...

kernel: vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets

A flaw was found in the vmxnet3 virtual network device driver within the Linux kernel. When processing Geneve-encapsulated packets, the vmxnet3gethdrlen function can incorrectly interpret header information, leading to a mismatch between expected and actual packet protocols or IP versions. This c...

CVE-2026-98705

A flaw was found in the Linux kernel's mac80211 wireless subsystem. When wireless mesh proxy paths are removed or expire, the interface path counter is decremented without having been accounted for during path creation. An attacker can exploit this accounting flaw through rapid proxy path churn,...

CVE-2026-98704

A flaw was found in the Linux kernel's mac80211 wireless subsystem. When associating with a wireless network profile that omits certain configuration parameters, the system prematurely frees internal data structures and subsequently reads the freed memory during connection setup. A malicious acce...

CVE-2026-98703

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local privileged user can cause a Denial of Service DoS by writing an invalid index value to the fixed-rate debugfs debug filesystem interface. Due to missing input validation, the kernel uses the value to access data outside...

CVE-2026-98701

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When adding mesh network routes, failed or duplicate path requests do not release reserved slot quotas. An adjacent attacker could exploit this issue by repeatedly triggering failed path additions to exhaust the mesh...

Security update for the Linux Kernel (Live Patch 56 for SUSE Linux Enterprise 15 SP4)

This update for the SUSE Linux Enterprise Kernel 5.14.21-150400.24.225 fixes various security issues: The following security issues were fixed: CVE-2026-53131: netfilter: require Ethernet MAC header before using ethhdr bsc1269775. CVE-2026-63794: KVM: SVM: Fix page overflow in sevdbgcrypt for...
