Canonical Outs New Linux Kernel Security Updates for Ubuntu 19.04 and 18.04 LTS

Canonical released new Linux kernel security updates for Ubuntu 19.04 (Disco Dingo) and Ubuntu 18.04 LTS (Bionic Beaver) operating system series to address various security vulnerabilities.

The new security updates are here to address a race condition (CVE-2019-11599) in Linux kernel when performing core dumps, and an integer overflow (CVE-2019-11487) when referencing counting pages. Both issues affect only Ubuntu 19.04 systems and could allow a local attacker to crash the system by causing a denial of service (DoS attack) or possibly execute arbitrary code.

On Ubuntu 18.04 LTS systems, the new security patch fixes a flaw (CVE-2019-11085) discovered by Adam Zabrocki in Linux kernel’s Intel i915 kernel mode graphics driver, which fai… (read more)

Linus Torvalds Kicks Off Development of Linux Kernel 5.3 as First RC Is Out Now

Linus Torvalds has kicked off the development of the Linux 5.3 kernel series, which will be the next major Linux kernel branch to be released this fall in early September.

The two-week merge window from the Linux 5.2 kernel series, which is now ready for mass deployments, is now closed, so the development cycle of Linux kernel 5.3 has kicked off over the weekend with the first RC (Release Candidate) ready for download and testing. According to Linus Torvalds, Linux kernel 5.3 RC1 is a pretty big release, but not the biggest ever.

“This is a pretty big release, judging by the commit count. Not the biggest ever (that honour still goes to 4.9-rc1, which was exceptionally big), and we’ve had a couple of comparable ones (4.12, 4.15 and 4.19 were also big merge windows), but it’s definitely up there,” said Linus Torvalds in a < ...

The Mageia 7 release, which arrived earlier this month, did not worked well on the new AMD Ryzen 3000-series systems, which failed to start up and blocked the installation of Mageia Linux.

“The timing for Mageia 7, just prior to the recent release of the new AMD Ryzen 3000 series of CPU’s, didn’t play nicely. Namely, there was an issue with the system starting up on these new CPU’s that prevented any type of installation, except for a net install,” explai… (read more)
