Title
EDAC/skx_common: Fix general protection fault
Summary
In the Linux kernel, the following vulnerability has been resolved: EDAC/skx_common: Fix general protection fault After loading i10nm_edac (which automatically loads skx_edac_common), if unload only i10nm_edac, then reload it and perform error injection testing, a general protection fault may occur: mce: [Hardware Error]: Machine check events logged Oops: general protection fault ... ... Workqueue: events mce_gen_pool_process RIP: 0010:string+0x53/0xe0 ... Call Trace: <TASK> ? die_addr+0x37/0x90 ? exc_general_protection+0x1e7/0x3f0 ? asm_exc_general_protection+0x26/0x30 ? string+0x53/0xe0 vsnprintf+0x23e/0x4c0 snprintf+0x4d/0x70 skx_adxl_decode+0x16a/0x330 [skx_edac_common] skx_mce_check_error.part.0+0xf8/0x220 [skx_edac_common] skx_mce_check_error+0x17/0x20 [skx_edac_common] ... The issue arose was because the variable 'adxl_component_count' (inside skx_edac_common), which counts the ADXL components, was not reset. During the reloading of i10nm_edac, the count was incremented by the actual number of ADXL components again, resulting in a count that was double the real number of ADXL components. This led to an out-of-bounds reference to the ADXL component array, causing the general protection fault above. Fix this issue by resetting the 'adxl_component_count' in adxl_put(), which is called during the unloading of {skx,i10nm}_edac.

During\nthe reloading of i10nm_edac, the count was incremented by the actual number\nof ADXL components again, resulting in a count that was double the real\nnumber of ADXL components. This led to an out-of-bounds reference to the\nADXL component array, causing the general protection fault above.\n\nFix this issue by resetting the \u0027adxl_component_count\u0027 in adxl_put(),\nwhich is called during the unloading of {skx,i10nm}_edac."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
