* CVE-2020-8835 - SAUCE: bpf: undo incorrect __reg_bound_offset32 handling -- Thadeu Lima de Souza Cascardo <casca...@canonical.com> Thu, 26 Mar 2020 17:51:28 -0300 ** Changed in: linux (Ubuntu Focal) Status: Confirmed => Fix Released ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2020-8835 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1867903 Title: Focal update: v5.4.26 upstream stable release Status in linux package in Ubuntu: Fix Released Status in linux source package in Focal: Fix Released Bug description: SRU Justification Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from a mainline/stable Linux tree or a minimally backported form of that patch. The following upstream stable patches should be included in the Ubuntu kernel: v5.4.26 upstream stable release from git://git.kernel.org/ Linux 5.4.26 net/smc: cancel event worker during device
