RLSA-2026:19365 Important: jq security update

jq is a lightweight and flexible command-line JSON processor. jq is like sed for JSON data. You can use it to slice, filter, map, or transform structured data with the same ease that sed, awk, grep, or similar applications allow you to manipulate text. Security Fixes: jq: out-of-bounds read in...

CVE-2026-46231

CVE-2026-46231 concerns the Linux kernel’s batman-adv code. When batadv_bla_add_claim() fails to insert a new claim into its hash, a reference to the target backbone_gw could be leaked. The vulnerability arises from not releasing that reference on the error path, potentially allowing a backbone_g...

CVE-2026-46145

The CVE-2026-46145 vulnerability affects the Linux kernel, specifically the RDMA/mana component. A user-supplied rx_hash_key_len value supplied via a uAPI structure is blindly passed to memcpy, enabling localized kernel memory corruption if bounds checks are not enforced. Reports from multiple so...
