kernel: NFSv4: include MAY_WRITE in open permission mask for O_TRUNC

A flaw was found in the Linux kernel's NFSv4 implementation. A local user could exploit a vulnerability where opening a file with OTRUNC truncate and ORDONLY read-only flags would bypass the necessary write permission checks. This oversight allows an attacker to truncate a file without having...

kernel: net: ipv6: use-after-free in fib6_rule_suppress due to stale res->rt6 pointer

A use-after-free vulnerability was found in the Linux kernel's IPv6 FIB rule lookup path. In fib6rulesuppress, when a route is suppressed and released via ip6rtputflags, the res-rt6 pointer is not cleared. If no later rule supplies a replacement route, fib6rulelookup returns the stale freed rt6in...

kernel: s390/cpum_sf: Handle CPU hotplug remove during sampling

A vulnerability was found in the Linux Kernel. This issue affects performance monitoring on the s390 architecture during specific CPU hotplug scenarios...

kernel: NFSv4/flexfiles: reject zero filehandle version count

A flaw was found in the Linux kernel's NFSv4 Network File System version 4 flexfiles component. This vulnerability occurs when the fflayoutalloclseg function processes a malformed flexfiles layout that specifies a zero filehandle version count. An attacker could exploit this by providing a...

kernel: zram: fix use-after-free in zram_bvec_write_partial()

A flaw was found in the Linux kernel, specifically within the zram module. This vulnerability is a use-after-free error, where the system attempts to use a piece of memory after it has been freed. This occurs when the zrambvecwritepartial function allows an asynchronous read to write into a page...

kernel: Kernel: Remote out-of-bounds write in RDMA/siw

A flaw was found in the Linux kernel's Soft iWARP siw driver. A remote attacker, by sending specially crafted Read Response segments that exceed the requested length, can trigger an out-of-bounds write. This vulnerability can lead to memory corruption, potentially causing a kernel crash or...

kernel: NFSv4/pNFS: reject zero-length r_addr in nfs4_decode_mp_ds_addr

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...

kernel: nfsd: fix posix_acl leak on SETACL decode failure

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...

kernel: pNFS: Fix use-after-free in pnfs_update_layout()

A flaw was found in the Linux kernel's parallel Network File System pNFS component. An issue in the pnfsupdatelayout function causes a use-after-free vulnerability due to incorrect ordering of memory management operations. This flaw can be triggered when the system attempts to update a pNFS layou...

kernel: AMD-SN-7061: Safe RET Interrupt Vulnerability

An attacker executing code on affected system could inject an interrupt at a precise moment to disrupt "Safe RET", the default Linux mitigation for speculative Return Overflow SRSO, which could potentially weaken that protection and may result in information disclosure...

kernel: bonding: alb: fix UAF in rlb_arp_recv during bond up/down

A flaw was found in the Linux kernel's bonding driver, specifically within the Active-Backup Load Balancing ALB receive path. A local attacker can trigger a Use-After-Free UAF vulnerability in the rlbarprecv function by rapidly bringing a bond interface up and down while receiving Address...

COPY-FAIL-CVE-2026-31431

This is a public Proof-of-Concept PoC for CVE-2026-31431 "Copy Fail", a Linux kernel local privilege escalation vulnerability CVSS 7.8 affecting most major distributions since 2017. It corrupts the page cache of a setuid binary like /usr/bin/su using the kernel's AFALG crypto API + splice, allowi...

SUSE CVE-2026-72374

In the Linux kernel, the following vulnerability has been resolved: afs: Fix callback service message parsers to pass through -EAGAIN The AFS filesystem client uses an rxrpc server to listen for callback notifications. Each callback call type handler has a delivery function that parses the incomi...

SUSE CVE-2026-72375

In the Linux kernel, the following vulnerability has been resolved: afs: Fix reinitialisation of the inode, in particular -lockwork It seems that initalising afsvnode::lockwork a single time in the slab's init function isn't sufficient for workstructs. This results in the DEBUGOBJECTS debugging...

SUSE CVE-2026-72378

In the Linux kernel, the following vulnerability has been resolved: afs: Fix error code in afsextractvladdrs The error codes on these paths are only set on the first iteration through the loop. Set the correct error code on every iteration...
