kernel: netfilter: nf_conntrack: use get_unaligned_be32() in tcp_sack()

A flaw was found in the Linux kernel's netfilter connection tracking subsystem. The TCP option processing mechanism improperly assumes memory alignment when reading packet headers. A remote attacker could exploit this vulnerability by sending crafted TCP packets with misaligned SACK options throu...

kernel: Linux kernel: Denial of Service in QFQ scheduler via child qlen manipulation

A flaw was found in the Linux kernel's Quick Fair Queuing QFQ scheduler. The QFQ class deactivation logic incorrectly relies on a child qdisc's queue length qlen to determine if a class is active. A local user with CAPNETADMIN capabilities can manipulate the child qlen into an unexpected state...

kernel: gfs2: Fix slab-use-after-free in qd_put

A flaw was found in the Linux kernel's GFS2 file system. During filesystem shutdown, quota data objects were freed without being properly removed from the Least Recently Used LRU list. This oversight could lead to a use-after-free vulnerability, where the system attempts to access memory that has...

kernel: net/sched: act_ct: Only release RCU read lock after ct_ft

A flaw was found in the Linux kernel. A race condition in the actct module, specifically during the flow table lookup, can lead to a Use-After-Free UAF vulnerability. This occurs because a critical lock is released prematurely, allowing a memory object to be freed while still in use. An attacker...

kernel: gfs2: add some missing log locking

A flaw was found in the Linux kernel's Global File System 2 GFS2 component. The gfs2logd function, responsible for log flushing, calls several log flushing functions without holding the required lock. This omission allows concurrent transactions to access shared resources without proper exclusion...

kernel: net: ip6_gre: require CAP_NET_ADMIN in the device netns for changelink

A flaw was found in the Linux kernel's ip6gre and ip6erspan tunnel drivers. The changelink functions in these drivers do not adequately verify administrative capabilities CAPNETADMIN across different network namespaces. This allows a local attacker, who has CAPNETADMIN in one network namespace bu...

kernel: ipvlan: inherit needed_headroom and needed_tailroom from phy_dev

A flaw was found in the Linux kernel's ipvlan component. The ipvlan devices do not properly inherit neededheadroom and neededtailroom from the physical device phydev. This can lead to insufficient space being reserved for packet headers and trailers, potentially causing memory corruption, such as...

kernel: nvme: add missing SRCU grace period in error path

A flaw was found in the NVMe Non-Volatile Memory Express driver of the Linux kernel. The nvmeallocns function's error handling path fails to wait for all SRCU Sleepable Read-Copy Update readers to complete before freeing a namespace structure. This oversight allows a concurrent reader to access a...

kernel: nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()

A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express input/output control ioctl handling. An unprivileged local user could exploit this vulnerability by bypassing access checks in the NVMEIOCTLSUBMITIO function. This allows them to perform unauthorized I/O operations on a...

kernel: KVM: s390: vsie: zero stale crypto bits

A flaw was found in the Linux kernel's KVM s390 Virtual Shared Inter-Partition Emulation VSIE component. When shadowing crypto access bits from a format0 apcb, stale crypto bits were not properly cleared. This oversight could allow a nested guest to potentially access a device that should no long...

kernel: ipvs: clear the svc scheduler ptr early on edit

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. During the ipvseditservice operation, the svc-scheduler pointer is cleared too late when unbinding an old scheduler. This improper handling allows packets to access previously freed scheduler data, leading to a use-after-fre...
