When the lookup fails like\nwhen a module is being loaded or unloaded, 'modname' holds a garbage\nvalue, passes the 'if (modname)' check, and is dereferenced by\nseq_printf().\n\n  Oops: general protection fault\n  RIP: 0010:string+0x48/0xe0\n  Call Trace:\n   vsnprintf+0x1f5/0x650\n   seq_printf+0x8e/0xb0\n   print_rec+0x6c/0xc0\n   t_show+0x4c/0x440\n   seq_read_iter+0x119/0x480\n\nThis can be triggered by reading available_filter_functions while a\nmodule is being loaded or unloaded.\n\nInitialize both variables so a failed lookup skips the module name.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0e5ff07be834abaf4280e1dca7f9591e339d0960","tags":[]},{"url":"https://git.kernel.org/stable/c/7271c064dd60d4456c5b90da757acd9420d06697","tags":[]},{"url":"https://git.kernel.org/stable/c/753d5cba113a52cb155428f4ea93a4b0148c4bf1","tags":[]},{"url":"https://git.kernel.org/stable/c/8932e5a4df110a25578728526bb5a3dbc849d8a2","tags":[]},{"url":"https://git.kernel.org/stable/c/d97dba9ff13987d1fc415408557a54adde980311","tags":[]},{"url":"https://git.kernel.org/stable/c/e2e6fb972bfec4a0551bc7c185bdb17f78f94997","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
