CVE-2026-52986

The CVE-2026-52986 issue affects the Linux kernel netfilter nf_conntrack_sip module, where unsafe port parsing on non-NUL-terminated data allowed malformed SIP packets to affect conntrack processing. The fix introduces a dedicated sip_parse_port() that validates each digit against the buffer limi...

CVE-2026-52921

A flaw was found in the Linux kernel's netfilter ipset component. Specifically, certain hash set variants such as hash:ip,mark and hash:ip,port that iterate IPv4 ranges with a 32-bit iterator do not correctly stop at the end of the requested range. This can cause the iteration to advance beyond t...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: iomap: The read range is adjusted correctly for positions that are not block-aligned. The iomapadjustreadrange function assumes that the position and length passed in are block-aligned. However, this is not always the case, as...

Astra Linux – Vulnerability in Chromium

In WebAudio, operations of reading and writing data outside of the allowed range in Google Chrome before version 146.0.7680.153 allowed a remote attacker to potentially exploit heap corruption through a crafted HTML page. Chromium security severity: High...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: Wifi: rtlwifi: 8192cu: fixed a situation where TID was out of range in rtl92cu TxFillDesc. The TID obtained from ieee80211gettid might be out of range of the array size of staEntry-tids, so check that TID is less than...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: media: dvb-usb: dtv5100: A out-of-bounds access occurred in dtv5100i2cmsg. The rlen value is a user-controlled value, but dtv5100i2cmsg does not check the size of the rlen value. Therefore, if the rlen value is set to a value...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: tpm2-sessions: Fixed an out-of-range indexing issue in namesize. namesize does not have any range checks; it simply indexes using TPMALGID, which could lead to memory corruption in extreme cases. The issue is addressed by only...
