PSA: Users running Linux on laptops with Intel processors should avoid Linux Kernel 5.19.12 due to an error that might physically harm the display. Fortunately, kernel 5.19.13 has already fixed the issue. Versions 6.0 and 6.1 have also begun rolling out with many significant changes.
Recent reports from Intel laptop users running Linux Kernel 5.19.12 describe "white flashing" on their screens. A Linux engineer found that the issue could ruin the LCD, urging users to immediately roll back to an earlier iteration. The critical flaw prompted developers to issue a quick update.
The problem appears to originate from a faulty Intel graphics driver, which Linux kernel engineer Ville Syrjal describes as a bad panel power sequencing delay. Greg Kroah-Hartman, the developer who released 5.19.13, said that users should only upgrade to the new kernel if they're experiencing this issue.

Released for most major distros this week, Linux Kernel 6.0 supports the newest hardware architectures, including Raptor Lake, Meteor Lake, Arc Alchemist, and RDNA 3. [...]
Kernel 6.1 closes a significant Bluetooth security hole and makes the first steps towards supporting the Rust programming language, which Google uses to develop Android. [...]
