You're not the only ones who have bugs reported... we're got one and Arch as well. I sent this email to the list a week ago; I don't know where it got lost...
--- Hi, This patch also fixes an issue introduced by the original patch involving dual booting: grub-mount seg faults when trying to mount an ntfs volume, e.g., when grub-mkconfig is run. There are bugs for this on fedora [1] and arch [2], so further review of this patch is really appreciated! thanks! marta [1] https://bugzilla.redhat.com/show_bug.cgi?id=2350327 [2] https://gitlab.archlinux.org/archlinux/packaging/packages/grub/-/issues/11 On Sat, Mar 15, 2025 at 3:14 PM Eric Valette <eric.vale...@gmail.com> wrote: > On 15/03/2025 08:54, Felix Zielcke wrote: > > Hi, > > > > on Debian we got a bug report with a segfault in grub-mount when we > > added the CVE fixes to it: > > > > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1100470 > > > > It crashes on all 3 Windows NTFS Partitions with this: > > > > Program received signal SIGSEGV, Segmentation fault. > > Download failed: Invalid argument.
