grub2: commands/extcmd: Missing check for failed allocation

A flaw was found in grub2 where the grubextcmddispatcher function calls grubarglistalloc to allocate memory for the grub's argument list. However, it fails to check in case the memory allocation fails. Once the allocation fails, a NULL point will be processed by the parseoption function, leading...

xorg: xwayland: Use of uninitialized pointer in compRedirectWindow()

An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow will return a BadAlloc error without validating the window tree marked just before, which leaves the...
