I'm on my way to #LABScon25 @labscon_io : Thanks @binarly_io for making it possible. Hit me up if you wanna chat about vuln research/exp-dev, automated binary analysis and effective mitigations against classes of issues @grsecurity . I am also helping hiring APT hunters (infra-structure).

The @Qualys TRU has identified two related local privilege escalation CVEs in openSUSE, SUSE Linux Enterprise, and libblockdev via the udisks daemon. Due to the ease of exploitation, immediate patching is strongly recommended. @saeed4bbasi explains: bit.ly/3SSjho2
