This is a note to let you know that I've just added the patch titled net: phy: dp83869: fix memory corruption when enabling fiber to the 6.11-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-phy-dp83869-fix-memory-corruption-when-enabling-.patch and it can be found in the queue-6.11 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 8f66def7f96ed250650de6f39aeed8a8d71c7d91 Author: Ingo van Lil <inguin@xxxxxx> Date: Wed Oct 2 18:18:07 2024 +0200 net: phy: dp83869: fix memory corruption when enabling fiber [ Upstream commit a842e443ca8184f2dc82ab307b43a8b38defd6a5 ] When configuring the fiber port, the DP83869 PHY driver incorrectly calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit number (10). This corrupts some other memory location -- in case of arm64 the priv pointer in the same structure. Since the advertising flags are updated from supported at the end of the function the incorrect line isn't needed at all and can be removed.
