CVE-2026-64190

The CVE-2026-64190 entry describes a Linux kernel race in net: team where __team_change_mode() clears team->ops with memset() while a concurrent team_xmit() under RCU can read ops.transmit and call a NULL pointer, causing a kernel NULL pointer dereference. It requires a mode change (CAP_NET_AD...

CVE-2026-64190 net: team: fix NULL pointer dereference in team_xmit during mode change

In the Linux kernel, the following vulnerability has been resolved: net: team: fix NULL pointer dereference in teamxmit during mode change teamchangemode clears team-ops with memset before restoring safe dummy handlers via teamadjustops. A concurrent teamxmit running under RCU on another CPU can...

CVE-2026-64189

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix race between dump and ipsetlist resize The release path of ipsetdumpdo and ipsetdumpdone read inst-ipsetlist via ipsetrefnetlink, a plain rcudereferenceraw of the array pointer. These run from netlinkrecvmsg...

CVE-2026-64188

In the Linux kernel RMNET net path, CVE-2026-64188 stems from use-after-free: rmnet_dellink() frees a rmnet_endpoint with kfree() while RCU readers may still reference ep->egress_dev, risking a fault in the receive path. The fix adds an rcu_head to struct rmnet_endpoint and replaces kfree() wi...

In the Linux kernel, the following vulnerability has been resolved: xfs: fail recovery on a committed log item with no regions If the first op of a transaction is a bare transaction header len == sizeofstruct xfstransheader, xlogrecoveraddtotrans adds an item but no region, leaving it on ritemq...

USN-8569-1 linux-hwe-7.0 vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

USN-8570-1 linux-gcp-6.17, linux-realtime-6.17 vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Foo-over-UDP FOU; - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Drivers core; - Null block...

USN-8570-1: Linux kernel vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Foo-over-UDP FOU; - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Drivers core; - Null block...

USN-8568-1: Linux kernel (OEM) vulnerabilities

It was discovered that some AMD Zen 2 processors did not properly isolate shared resources in the operation cache. A local attacker could possibly use this issue to corrupt instructions executed at a higher privilege level, resulting in privilege escalation. CVE-2025-54518 Several security issues...

CVE-2026-64168

A flaw was found in the Linux kernel's spi-sprd driver. This vulnerability occurs when the driver attempts to release Direct Memory Access DMA channels after a DMA setup failure during the probe phase. Without properly checking if DMA is enabled, the driver may try to dereference an invalid point...

CVE-2026-53402

A flaw was found in the Linux kernel's framebuffer console fbcon component. When the fbcondosetfont function fails, the system's error handling does not correctly restore the font state, leading to a desynchronized terminal. A local user can exploit this by providing character indices that cause ...

CVE-2026-53400

A flaw was found in the Linux kernel, specifically within its I2C Inter-Integrated Circuit core component. This vulnerability arises from a timing issue during the registration of I2C adapters, where an adapter could be accessed before it is fully prepared. This premature access to uninitialized...

CVE-2026-64112

A flaw was found in the Linux kernel's Rados Block Device RBD module. A race condition exists in the lockdwork draining mechanism during the unmapping of an image. This allows the lockdwork to be re-queued after it is expected to be finalized, potentially leading to rbdacquirelock executing on...

CVE-2026-53397

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...
