CVE-2025-68380 — wifi: ath11k: fix peer HE MCS assignment

Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: fix peer HE MCS assignment

In ath11k_wmi_send_peer_assoc_cmd(), peer's transmit MCS is sent to firmware as receive MCS while peer's receive MCS sent as transmit MCS, which goes against firmwire's definition.

While connecting to a misbehaved AP that advertises 0xffff (meaning not supported) for 160 MHz transmit MCS map, firmware crashes due to 0xffff is assigned to he_mcs->rx_mcs_set field.

Ext Tag: HE Capabilities [...] Supported HE-MCS and NSS Set [...] Rx and Tx MCS Maps 160 MHz [...] Tx HE-MCS Map 160 MHz: 0xffff

Swap the assignment to fix this issue.

As the HE rate control mask is meant to limit our own transmit MCS, it needs to go via he_mcs->rx_mcs_set field. With the aforementioned swapping done, change is needed as well to apply it to the peer's receive MCS.

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM). An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege escalation, or possibly escape a container. (LP: #2143853)

It was discovered that some AMD Zen 5 processors supporting RDSEED instruction did not properly handle entropy, potentially resulting in the consumption of insufficiently random values. A local attacker could possibly use this issue to influence the values returned by the RDSEED instruction causing loss of confidentiality and integrity. (CVE-2025-62626)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - S390 architecture; - x86 architecture; - Block layer subsystem; - Cryptographic API; - Compute Acceleration Framework; - ATM drivers; - Network block device driver; - Bluetooth drivers; - Data acquisition framework and drivers; - Hardware crypto device drivers; - Device frequency scaling framework; - Intel Stratix 10 firmware drivers; - GPIO subsystem; - GPU drivers; - Microsoft Hyper-V drivers; - CoreSight HW tracing drivers; - IIO subsystem; - InfiniBand drivers; - Input Device core drivers; - Input Device (Tablet) d…
