kernel: flow_dissector: do not dissect PPPoE PFC frames

A flaw was found in the Linux kernel's flow dissector. This vulnerability allows a remote attacker to cause a Denial of Service DoS by sending a specially crafted Point-to-Point Protocol over Ethernet PPPoE Protocol Field Compression PFC frame to an affected system. The incorrect processing of...

kernel: ipv6: add NULL checks for idev in SRv6 paths

A flaw was found in the Linux kernel. Missing null pointer checks in the IPv6 Segment Routing SRv6 implementation, specifically within the seg6hmacvalidateskb and ipv6srhrcv functions, can occur when an IPv6 device lacks proper configuration. This oversight may allow an attacker to trigger a null...

kernel: ipv6: prevent possible UaF in addrconf_permanent_addr()

A flaw was found in the Linux kernel's IPv6 networking subsystem. Specifically, a Use-after-Free UaF vulnerability exists within the addrconfpermanentaddr function. This issue arises when the system attempts to access an IPv6 address after it has been freed, which could allow an attacker to cause...

kernel: vxlan: do not reuse cached ip_hdr() value after skb_tunnel_check_pmtu()

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN module. This vulnerability occurs because a cached IP header pointer is improperly reused after a Path Maximum Transmission Unit PMTU check. When the packet's head is modified during the PMTU check, the old cached IP header point...

kernel: rhashtable: clear stale iter->p on table restart

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free, occurs in the rhashtable component when the system improperly handles hash table restarts. An attacker could potentially exploit this by causing the system to access memory that has already been released, which m...

kernel: udp: Fix wildcard bind conflict check when using hash2

A flaw was found in the Linux kernel's User Datagram Protocol UDP implementation. When a significant number of UDP sockets are bound to specific local addresses on the same port, the kernel's conflict detection mechanism can fail. This allows a local attacker to bind to a wildcard address on a po...

kernel: io_uring/poll: fix signed comparison in io_poll_get_ownership()

A flaw was found in the Linux kernel's iouring/poll component. A logic error exists in the iopollgetownership function due to an incorrect signed comparison. This flaw prevents the necessary slowpath from being triggered when the IOPOLLCANCELFLAG is set, potentially leading to unexpected behavior...

kernel: fuse: clear intr_entry in fuse_resend and fuse_remove_pending_req

A flaw was found in the Linux kernel's fuse component. When a fuse request is interrupted and then resent, a specific interrupt entry intrentry is not properly cleared. If the requesting task subsequently receives a fatal signal, this uncleared entry can lead to a use-after-free condition. This...
