USN-8644-2: Linux kernel (GCP) vulnerabilities

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: - File systems infrastructure; - OCFS2 file system; - B.A.T.M.A.N. meshing protocol; - SCTP protocol; - TIPC protocol...

CVE-2026-72235

A flaw was found in the Linux kernel batman-adv component. The batadvinterfacerx function, responsible for handling network packets, can reallocate its internal buffer. However, a pointer to the ethernet header is not correctly updated after this reallocation. This oversight leads to a...

CVE-2026-72234

A flaw was found in the Linux kernel's batman-adv module. When the pskbmaypull function is called by batadvgetvid, it can reallocate a buffer. However, a pointer to the old buffer, specifically unicastpacket, was not correctly reassigned, leading to a use-after-free condition. This memory...

CVE-2026-72233

A flaw was found in the batman-adv component of the Linux kernel. This vulnerability occurs when a buffer is reallocated, but existing pointers are not updated, leading to a use-after-free condition. A local attacker could potentially exploit this to cause a system crash denial of service or, in...

CVE-2026-72232

A flaw was found in the batman-adv component of the Linux kernel. A local user with extended Berkeley Packet Filter eBPF traffic control TC hook access could exploit this by attaching a TC filter that truncates a packet and redirects it to a batman-adv interface. The batadvinterfacetx function th...

CVE-2026-72229

A flaw was found in the batman-adv component of the Linux kernel. When a mesh interface is registered, an untagged VLAN object is created. If the network device netdev registration fails due to a veto, the cleanup process does not properly free this object. This can lead to a memory leak,...

CVE-2026-72228

A flaw was found in the batman-adv component of the Linux kernel. This vulnerability occurs during the processing of network packets that have fragmented data. Specifically, if a packet's fragmented data fails a preparation step called linearization, a reference to a network interface primaryif i...

CVE-2026-72227

A flaw was found in the Linux kernel's batman-adv component. An out-of-bounds read vulnerability exists in the mcast module due to an incorrect size check when accessing the numdests header. This flaw could allow an attacker to read sensitive information from memory or cause a denial of service...

CVE-2026-72226

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module. An integer overflow can occur when calculating the length of a Translation Table Type-Length-Value TVLV unicast message. This overflow can lead to invalid safety checks, allowing an...

CVE-2026-72230

A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced fragmentation module of the Linux kernel. The batadvfragsendpacket function, responsible for sending fragmented packets, does not properly free allocated memory when a packet is deemed unfragmentable due to ...

CVE-2026-72231

A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking module of the Linux kernel. An incorrect check during the handling of TT Topology Table requests can prevent the proper cleanup of request nodes when send buffer allocation fails. This can lead to a remote attacker...
