CVE-2026-90355

CVE-2026-90355 affects the mt76/mt7996 WiFi driver in the Linux kernel. After a full chip reset, the reset path frees link structures without clearing the valid_links bits or the MLD index masks. When mac80211 replays its reconfiguration, mt7996_vif_link_add() short-circuits because the link IDs ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ip6gre: made ip6greheader more robust. Over the years, syzbot has identified many ways in which the kernel can crash due to issues related to ip6greheader. This involves the ability of team or bonding drivers to dynamically chang...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: ipv6: mcast: added RCU protection to mldnewpack The mldnewpack function can be called without holding RTNL or RCU. It should be noted that we can no longer use sockallocsendskb, because ipv6.igmpsk relies on GFPKERNEL...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: ipv6: mcast: fixed a data race in ipv6mcdown / mldifcwork. idev-mcifccount can be written without proper locking. Originally reported by syzbot 1. This issue was fixed by encapsulating calls to mldifcstopwork and mldgqstopwork...

kernel: wifi: iwlwifi: mld: fix TSO segmentation explosion when AMSDU is disabled

A flaw was found in the Linux kernel's iwlwifi MLD driver. When the Aggregated MAC Service Data Unit AMSDU feature is disabled, the driver incorrectly processes Transmit Segmentation Offload TSO requests. This can lead to a flood of micro-frames on the transmit ring, resulting in memory corruptio...

kernel: wifi: iwlwifi: mld: validate sta_mask before ffs() in BA session handlers

A flaw was found in the Linux kernel's iwlwifi Intel Wireless WiFi driver. This vulnerability allows an attacker to cause an out-of-bounds memory access in the WiFi Block Acknowledgement BA session handlers. This occurs when the stamask value is zero, leading to an incorrect station ID calculatio...
