kernel: smb: client: clear setuid/setgid bit on write with cifsacl/modefromsid/posix extensions
A flaw was found in the Linux kernel's Server Message Block SMB client. When a file with the setuid or setgid bit is written to on certain Common Internet File System CIFS mounts specifically those using 'cifsacl', 'modefromsid' options, or SMB3.1.1 POSIX extensions, the kernel fails to properly...
kernel: tcp: restrict SO_ATTACH_FILTER to priv users
A flaw was found in the Linux kernel's handling of TCP sockets. An unprivileged application can exploit this vulnerability by attaching a Berkeley Packet Filter BPF using the SOATTACHFILTER option. This allows the application to conduct a side-channel attack, leading to the leakage of sensitive T...
kernel: net/iucv: filter frames in afiucv_hs_rcv() by ingress device
A flaw was found in the Linux kernel's AFIUCV Advanced Program-to-Program Communication over IUCV network protocol implementation. The afiucvhsrcv function, responsible for receiving frames, does not properly filter incoming frames based on the ingress network device. This oversight allows a loca...
kernel: net/sched: serialize qdisc_rtab_list against concurrent get/put
A flaw was found in the Linux kernel's networking scheduler component. A race condition exists in the handling of rate tables qdiscrtablist due to a lack of proper locking during concurrent operations. A local attacker could exploit this by sending specially crafted network filter requests, leadi...
kernel: net/iucv: fix use-after-free of a severed iucv_path
A flaw was found in the Linux kernel. This use-after-free vulnerability exists in the net/iucv component. When a peer severs a connection, message notifications that still reference the freed connection path remain in a queue. A subsequent attempt to process these stale notifications can lead to...
kernel: net/packet: avoid fanout hook re-registration after unregister
A flaw was found in the Linux kernel's net/packet subsystem. A race condition can occur during the re-registration of a fanout hook after a network device has been unregistered. This issue arises when the packetsetring function attempts to re-add a fanout hook based on a stale state, potentially...
kernel: usb: usbfs: fix use-after-free of usb_device in usbdev_release()
A flaw was found in the Linux kernel's USB subsystem usbfs. An unprivileged local attacker with read/write access to a /dev/bus/usb node could exploit a use-after-free vulnerability. This occurs because the usbdevice structure is prematurely freed before all pending operations are completed...
kernel: ipvs: reload ip header after head reallocation
A flaw was found in the Linux kernel's IP Virtual Server IPVS module. When processing network packets, a buffer reallocation can leave an IP header pointer referencing freed memory. An attacker could exploit this use-after-free condition to cause a Denial of Service DoS by crashing the system or...

kernel: fuse: re-lock request before replacing page cache folio
A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. The fusetrymovefolio function, responsible for managing page cache folios, fails to re-lock a request after initially unlocking it on a successful path. This oversight allows another function, fusechanabort, to...
kernel: mptcp: options: reset DSS fields in case of unexpected size
A flaw was found in the Linux kernel's Multipath TCP mptcp implementation. A remote attacker could send specially crafted Data Sink Selection DSS options with an unexpected size. This could lead to data inconsistency or the access of uninitialized data, potentially resulting in information...
kernel: net: gro: fix double aggregation of flush-marked skbs
A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. An attacker could exploit this by sending specially crafted network packets that cause a double aggregation of flush-marked socket buffers skbs. This issue arises from a missing flush check, which allows...
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...
kernel: writeback: fix race between cgroup_writeback_umount() and inode_switch_wbs()
A flaw was found in the Linux kernel. A race condition exists between the cgroupwritebackumount and inodeswitchwbs functions when a container exits. This race can lead to a kernel panic, resulting in a denial of service. This vulnerability could be triggered by a local user by exiting a container...
