EUVD-2026-41669

In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In ip6appenddata, when the paged-allocation branch is taken MSGMORE / NETIFFSG / large fraglen, alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen;...

CVE-2026-53361

The CVE-2026-53361 vulnerability affects the Linux kernel’s af_unix path, where unix_gc() could observe gc_in_progress as false due to race conditions when scheduling GC work. The fix sets gc_in_progress to true inside unix_gc(), addressing a window where GC could be re-entered or confused by MSG...

EUVD-2026-41668

In the Linux kernel, the following vulnerability has been resolved: afunix: Set gcinprogress to true in unixgc. Igor Ushakov reported that unixgc could run with gcinprogress being false if the work is scheduled while running: Thread 1 Thread 2 Thread 3 -------- -------- -------- unixschedulegc...

CVE-2026-53360

The CVE affects the Linux kernel KVM-SEV/SNP path: when GHCB v2+ is in use, an OOB/heap-privacy flaw arises because end_entry is validated only against VMGEXIT_PSC_MAX_COUNT (253) instead of the actual buffer size, allowing a guest to read/write adjacent kmalloc-cg-32 objects via VMGEXITs. This c...

PT-2026-55697

Name of the Vulnerable Software and Affected Versions Linux Kernel affected versions not specified Description A use-after-free issue exists in the KVM x86 shadow paging implementation. The problem occurs when a Page Directory Entry PDE mapping is modified from outside the guest and a memslot is...

UBUNTU-CVE-2026-53357

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix UAF in l2capsockcleanuplisten vs l2capconndel btacceptdequeue unlinks a not-yet-accepted child from the parent accept queue and releasesocks it before returning, so the returned sk has no caller reference and is...

CVE-2026-53358

A flaw was found in the Linux kernel's Bluetooth L2CAP Logical Link Control and Adaptation Protocol implementation. This vulnerability arises from an incorrect order of acquiring locks during channel cleanup, which could lead to a race condition. This issue could potentially cause instability or...

CVE-2026-53357

A flaw was found in the Linux kernel's Bluetooth component. A Use-After-Free UAF vulnerability exists in the l2capsockcleanuplisten and l2capconndel functions. This flaw occurs due to a race condition during the cleanup of a listening socket and a concurrent Bluetooth HCI disconnect. An...

USN-8501-1 linux vulnerabilities

It was discovered that a logic flaw existed in the XFRM ESP-in-TCP subsystem in the Linux kernel when handling socket buffer fragments. This flaw is known as Fragnesia. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-43503 Several security issues...

USN-8493-2 linux-oracle-5.15 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: - RISC-V architecture; - Cryptographic API; - InfiniBand drivers; - IOMMU subsystem; - Network drivers; -...

USN-8499-1 linux-xilinx vulnerabilities

It was discovered that the Linux kernel algifaead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. CVE-2026-31431 It was discovered that the Linux kernel did n...

USN-8497-1 linux-lowlatency, linux-lowlatency-hwe-6.8 vulnerabilities

It was discovered that the Linux kernel did not properly handle shared page fragments during socket buffer operations, collectively known as Dirty Frag. A logic flaw existed in the XFRM ESP-in-TCP subsystem and in the RxRPC networking subsystem when processing paged fragments. A local attacker...

USN-8492-2 linux-aws-6.8, linux-gcp-6.8, linux-gke, linux-gkeop, linux-ibm-6.8, linux-nvidia-lowlatency, linux-oracle-6.8 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: - ARM64 architecture; - MIPS architecture; - PowerPC architecture; - x86 architecture; - Block layer subsystem; -...

USN-8488-2 linux-raspi 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 Several security issues were discovered in the Linux kernel. An attacker could...

EUVD-2026-41373

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: use chan timer to close channels in cleanuplisten l2capchanclose removes the channel from conn-chanl, which must be done under conn-lock. cleanuplisten runs under the parent sklock, so acquiring conn-lock would...
