The function udf_tgetblk is defined in udf/misc.c and returns the value of sb_getblk function that could be NULL. Then, epos.bh is used without any check, causing a possible NULL pointer dereference when sb_getblk fails.</p> <p>This fix adds a check to validate the value of epos.bh.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>udf: Fix NULL pointer dereference in udf_symlink function</p> <p>In function udf_symlink, epos.bh is assigned with the value returned by udf_tgetblk.
