kernel: crypto: af_alg - Cap AEAD AD length to 0x80000000
A flaw was found in the Linux kernel's afalg cryptography module. This vulnerability involves an arithmetic overflow when processing associated data lengths during the transmit buffer size check. A remote attacker could exploit this flaw by providing a specially crafted associated data length,...
kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()
A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...
kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read
A flaw was found in the Linux kernel's scsi: qla2xxx driver. A remote attacker, by sending a specially crafted Fibre Channel Protocol FCP response, could cause an integer underflow. This underflow leads to an out-of-bounds read when handling sense data, potentially disclosing sensitive memory...
kernel: mac802154: llsec: add skb_cow_data() before in-place crypto
A flaw was found in the Linux kernel's mac802154 IEEE 802.15.4 MAC security component. This vulnerability allows for data corruption and potential kernel crashes when cryptographic transformations are performed on shared network packet data without proper isolation. A remote attacker could exploi...
kernel: Bluetooth: SCO: fix race conditions in sco_sock_connect()
A flaw was found in the Linux kernel, specifically within its Bluetooth Synchronous Connection-Oriented SCO component. This vulnerability occurs due to race conditions when multiple connection attempts are made simultaneously on the same Bluetooth socket. This can lead to a use-after-free error,...
Important: Red Hat Security Advisory: kernel security update
An update for kernel is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...
kernel: selinux: check connect-related permissions on TCP Fast Open
A flaw was found in the Linux kernel's Security-Enhanced Linux SELinux module. When using TCP Fast Open, SELinux failed to properly check connect-related permissions. This oversight could allow a local attacker to bypass SELinux network access controls, potentially enabling unauthorized network...

kernel: net: bridge: use a stable FDB dst snapshot in RCU readers
A flaw was found in the Linux kernel. Inconsistent handling of local Forwarding Database FDB entries in the bridge networking component's RCU Read-Copy-Update readers can lead to a null-pointer dereference. A local attacker could exploit this by triggering a concurrent update to an FDB entry,...
SUSE CVE-2026-99015
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisock: Serialize dead-device detachment Rebinding an HCI socket after its controller is unregistered can race monitor control replay and crash the kernel. hcisockbind clears hcipisk-hdev and drops the device referenc...
SUSE CVE-2026-99036
In the Linux kernel, the following vulnerability has been resolved: dm: fix reading free memory in doresume When doresume calls dmtablegetmodenewmap, the call is done without holding any locks it only holds a reference to the md. It may be possible that another concurrent ioctl on the same device...
SUSE CVE-2026-99042
In the Linux kernel, the following vulnerability has been resolved: iouring/net: populate CONNECT filter fields for 24-byte sockaddrin6 ioconnectbpfpopulate fills connect.port and connect.v6addr for AFINET6 only when addrlen = sizeofstruct sockaddrin6, i.e. 28 bytes. The IPv6 connect paths accept...

PT-2026-128201
In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Zero OA buffer at allocation ttm bo type kernel BOs are not guaranteed to be zeroed on allocation and may contain data from previously freed pages. Since the OA buffer is mmap'able by userspace, this can expose stale...

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix data corruption with concurrent writes and O TRUNC cifs do truncate flushes dirty pages with filemap write and wait and truncates the file on the server, but in the old code both operations ran without holding i...
PT-2026-128121
In the Linux kernel, the following vulnerability has been resolved: sctp: validate chunk length in the inqueue parser SCTP chunks always include a four-byte generic header, but sctp inq pop currently accepts shorter declared lengths. A zero-length chunk leaves chunk end at the current header. Whe...
